If you haven’t already signed up for an Instaclustr account, refer our [support article](https://www.instaclustr.com/support/documentation/cassandra-add-ons/apache-spark/instaclustr-spark-with-ssl-configured-cassandra-cluster/) to sign up and create an account. 2. Once you have signed up for Instaclustr and verified your email, log in to the Instaclustr [console](https://console.instaclustr.com/) and click the *Create Cluster* button to create a new cluster. ![Location of Create Cluster Buttons](https://www.instaclustr.com/wp-content/uploads/2021/08/create-cluster-1024x555.png) 3. Under the *Application* section, enter an appropriate name for your cluster. Select Apache Cassandra as the base application and Amazon Web Services as the infrastructure provider. ‎ ![Application Selection Page](https://www.instaclustr.com/wp-content/uploads/2021/08/application-1024x557.png) 4. Under *Cassandra Setup*, select Apache Spark as an add-on. Note that we recommend that you enable *Use private IPs to broadcast for auto-discovery*. Do not enable *Client to Cluster Encryption.* If you wish to configure Apache Spark with an SSL configured Cassandra Cluster, you may refer to our [support article](https://www.instaclustr.com/support/documentation/cassandra-add-ons/apache-spark/instaclustr-spark-with-ssl-configured-cassandra-cluster/).‎ ![Location of Cassandra with spark on page](https://www.instaclustr.com/wp-content/uploads/2020/02/Cassandra-setup-1024x675.png) 5. Under the *Data Centre* section, select a Data Centre Region, a Cluster Network address block, the number of nodes for your application, and your desired node size. ‎‎ ![](https://www.instaclustr.com/wp-content/uploads/2021/08/data-centre-1024x540.png)If the data centre for your cluster is running on Amazon’s EBS infrastructure, you can choose to [encrypt your data with an AWS KMS key](https://www.instaclustr.com/support/documentation/useful-information/aws-ebs-encryption-and-kms-keys/).Please refer to our support article on [Network Address Allocation](https://www.instaclustr.com/support/documentation/useful-information/network-address-allocation/) to understand how we divide up the specified network range to determine the node IP addresses. 6. Accept the terms and conditions and click the *Create Cluster* button. The cluster will automatically provision and will be available for use once all nodes are in the running state. Set Up a Spark Client --------------------- To use our Spark cluster, you will need a client machine setup to submit jobs. Use the following steps to set up a client in AWS: 1. Provision a new Amazon EC2 instance (a virtual AWS server) with the following configuration: - **AMI:** Ubuntu Server 16.04 LTS (HVM), SSD Volume Type - **Instance Type**: t2.small is sufficient for this tutorial and sufficient for many use-cases ongoing - **VPC:** if possible, use a VPC with DNS resolution and DNS hostname enabled (Otherwise, refer to step 7 below). The VPC network range should not overlap with the network range of your instaclustr cluster. Also, ensure that the region of your VPC is the same as that of your newly created Cassandra and Spark cluster. 2. ssh to the newly launched server with ubuntu as username. 3. Download the spark version matching your instaclustr version. In this case, Spark 2.1.1: Shell <span style="font-weight: 400;">wget https://archive.apache.org/dist/spark/spark-2.3.2/</span><a href="https://archive.apache.org/dist/spark/spark-2.3.2/spark-2.3.2-bin-hadoop2.6.tgz"><span style="font-weight: 400;">spark-2.3.2-bin-hadoop2.6.tgz</span></a> 1 <span style="font-weight: 400;">wget https://archive.apache.org/dist/spark/spark-2.3.2/</span><a href="https://archive.apache.org/dist/spark/spark-2.3.2/spark-2.3.2-bin-hadoop2.6.tgz"><span style="font-weight: 400;">spark-2.3.2-bin-hadoop2.6.tgz</span></a> 4. Extract the Spark files: Shell <span style="font-weight: 400;">tar -xvf </span><a href="https://archive.apache.org/dist/spark/spark-2.3.2/spark-2.3.2-bin-hadoop2.6.tgz"><span style="font-weight: 400;">spark-2.3.2-bin-hadoop2.6.tgz</span></a> 1 <span style="font-weight: 400;">tar -xvf </span><a href="https://archive.apache.org/dist/spark/spark-2.3.2/spark-2.3.2-bin-hadoop2.6.tgz"><span style="font-weight: 400;">spark-2.3.2-bin-hadoop2.6.tgz</span></a> 5. Download the Spark Cassandra assembly Jar (this is a fat Jar built by Instaclustr to include all required dependencies, to be used for spark shell). The latest version available for your spark version should be accessible via the Connection Info page of Instaclustr console. Shell <span style="font-weight: 400;">wget </span><a href="https://static.instaclustr.com/spark/spark-cassandra-connector-assembly-2.3.2.jar"><span style="font-weight: 400;">https://static.instaclustr.com/spark/spark-cassandra-connector-assembly-2.3.2.jar</span> </a> 1 <span style="font-weight: 400;">wget </span><a href="https://static.instaclustr.com/spark/spark-cassandra-connector-assembly-2.3.2.jar"><span style="font-weight: 400;">https://static.instaclustr.com/spark/spark-cassandra-connector-assembly-2.3.2.jar</span> </a> 6. Install the Java Development Kit: Shell sudo apt-get update sudo apt-get install default-jdk 1 2 sudo apt-get update sudo apt-get install default-jdk 7. If you are not using a VPC with DNS resolution and DNS hostname enabled, you will need to change the hostname of the client to the IP so that it resolves when used by Spark (a bit of a hack – the right way is to edit /etc/hosts but this is quicker):If your spark version is equal or above 2.3.2 you will have to add SPARK\_PUBLIC\_DNS=<your\_ip> and SPARK\_LOCAL\_IP=<your\_ip> to the spark-env.sh in the conf directory of your spark installation. Shell sudo hostname 1 sudo hostname 8. If you will be building the final scala example, then install sbt: Shell <span style="font-weight: 400;">echo "deb https://repo.scala-sbt.org/scalasbt/debian all main" | sudo tee /etc/apt/sources.list.d/sbt.list</span> <span style="font-weight: 400;">echo "deb https://repo.scala-sbt.org/scalasbt/debian /" | sudo tee /etc/apt/sources.list.d/sbt\_old.list</span> <span style="font-weight: 400;">curl -sL "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0x2EE0EA64E40A89B84B2DF73499E82A75642AC823" | sudo apt-key add</span> sudo apt-get update sudo apt-get install sbt 1 2 3 4 5 <span style="font-weight: 400;">echo "deb https://repo.scala-sbt.org/scalasbt/debian all main" | sudo tee /etc/apt/sources.list.d/sbt.list</span> <span style="font-weight: 400;">echo "deb https://repo.scala-sbt.org/scalasbt/debian /" | sudo tee /etc/apt/sources.list.d/sbt\_old.list</span> <span style="font-weight: 400;">curl -sL "https://keyserver.ubuntu.com/pks/lookup?op=get&search=0x2EE0EA64E40A89B84B2DF73499E82A75642AC823" | sudo apt-key add</span> sudo apt-get update sudo apt-get install sbt Configure Client Network Access ------------------------------- As Spark has minimal security, we recommend that you access Spark from a peered VPC in AWS to increase the security of network-based access rules. To set up the peered VPC and allow connections from your VPC to the cluster, follow our support article on [Using VPC Peering AWS](https://www.instaclustr.com/support/documentation/cassandra/using-cassandra/connect-to-cassandra-cluster-vpc-peering-aws/). Note: When following the VPC Peering instructions, you must add your VPC network range to the Spark Allowed Addresses and the Cassandra Allowed Addresses. The Spark driver on your client machine needs to be able to connect to Cassandra as well as the Spark workers (to establish partition ranges). In addition to connections from the Spark Client to the cluster, the architecture of Spark means that the Spark Cluster needs to be able to connect to the clients. Enable this in AWS by editing the security group associated with your Spark Client to add an Inbound rule with the following values: - Type: Custom TCP Rule - Protocol: TCP - Port Range: 1024-65535 - Source: Custom IP, <your cluster network range> (viewable from the cluster details page in the Instaclustr console) Basic Interaction with Spark Shell ---------------------------------- We will now connect to the Spark cluster using the Spark Shell and run an analytic job. (**Note**: sometimes the log messages from Spark shell overwrite the shell prompt. If processing seems to have stopped with no prompt then hit the enter key to get a prompt.) 1. Find the IP addresses of the three Spark Masters in your cluster – this is viewable on the Apache Spark tab on the Connection Info page for your cluster.![Screenshot showing spark connection information](https://www.instaclustr.com/wp-content/uploads/2020/02/Spark-Cluster-Connection-Info-1024x527.png) 2. Log in to your Spark Client and run the following command (adjust keywords in <> to specify your spark master IPs, one of Cassandra IP, and the Cassandra password if you enabled authentication). For Spark 3, include the key value pair spark.sql.extensions=com.datastax.spark.connector.CassandraSparkExtensions with –conf. This option will enable Cassandra Specific Catalyst optimizations and functions. Shell cd ~/spark-2.1.1-bin-hadoop2.6/bin ./spark-shell --master spark://<spark\_master\_IP1>:7077,<spark\_master\_IP2>:7077,<spark\_master\_IP3>:7077 --conf spark.cassandra.connection.host=<cassandra\_private\_IP> --conf spark.cassandra.auth.username=iccassandra --conf spark.cassandra.auth.password=<iccassandra password> --conf spark.driver.host=<your\_ip> --jars ~/spark-cassandra-connector-assembly-2.0.2.jar 1 2 cd ~/spark-2.1.1-bin-hadoop2.6/bin ./spark-shell --master spark://<spark\_master\_IP1>:7077,<spark\_master\_IP2>:7077,<spark\_master\_IP3>:7077 --conf spark.cassandra.connection.host=<cassandra\_private\_IP> --conf spark.cassandra.auth.username=iccassandra --conf spark.cassandra.auth.password=<iccassandra password> --conf spark.driver.host=<your\_ip> --jars ~/spark-cassandra-connector-assembly-2.0.2.jar 3. Spark-shell should start without any errors. There will be a lot of log message. Once fully started you will see a prompt: “scala>”. 4. Some imports are necessary. For this simple job, enter the following at the prompt: Shell import org.apache.spark.{SparkConf, SparkContext} import org.apache.spark.SparkContext.\_ import com.datastax.spark.connector.\_ 1 2 3 import org.apache.spark.{SparkConf, SparkContext} import org.apache.spark.SparkContext.\_ import com.datastax.spark.connector.\_ 5. Now we can create an rdd and execute an action on it. Only the action (rdd.count) will trigger the calculation. In this case, we use the “system\_schema” keyspace that is used by cassandra to keep tracks of internals, such as the list of keyspaces. Shell val rdd = sc.cassandraTable("system\_schema","keyspaces") println("Row count: " + rdd.count) 1 2 val rdd = sc.cassandraTable("system\_schema","keyspaces") println("Row count: " + rdd.count) 6. You should see a lot of log messages followed by the row count message. Using Spark SQL from Spark Shell -------------------------------- Spark SQL allows you to run complex SQL queries against Cassandra data. The following step demonstrate how to execute a Spark SQL query against Cassandra using the Spark SQL connector. Execute these steps in the same Spark shell session where you executed the previous example: 1. Import the required libraries: Shell import org.apache.spark.sql.cassandra.\_ import org.apache.spark.sql 1 2 import org.apache.spark.sql.cassandra.\_ import org.apache.spark.sql 2. Create a temporary view to access datasets using Spark SQL: Shell val createDDL = """CREATE TEMPORARY VIEW keyspaces USING org.apache.spark.sql.cassandra OPTIONS ( table "keyspaces", keyspace "system\_schema", pushdown "true")""" spark.sql(createDDL) 1 2 3 4 5 6 7 8 val createDDL = """CREATE TEMPORARY VIEW keyspaces USING org.apache.spark.sql.cassandra OPTIONS ( table "keyspaces", keyspace "system\_schema", pushdown "true")""" spark.sql(createDDL) 3. Run queries on the temporary view: Shell spark.sql("SELECT \* FROM keyspaces").show val rdd1 = spark.sql("SELECT count(\*) from keyspaces") println("Row count: " + rdd1.first()(0)) 1 2 3 4 spark.sql("SELECT \* FROM keyspaces").show val rdd1 = spark.sql("SELECT count(\*) from keyspaces") println("Row count: " + rdd1.first()(0)) Using Spark SQL from Spark Shell for Spark 3 -------------------------------------------- 1. Create a Catalog Reference to your Cassandra Cluster Shell spark.conf.set(s"spark.sql.catalog.mycatalog", "com.datastax.spark.connector.datasource.CassandraCatalog") 1 spark.conf.set(s"spark.sql.catalog.mycatalog", "com.datastax.spark.connector.datasource.CassandraCatalog") 2. Create a keyspace and table in Cassandra using spark sql Shell spark.sql("CREATE DATABASE IF NOT EXISTS mycatalog.testks WITH DBPROPERTIES (class='SimpleStrategy',replication\_factor='1')") spark.sql("CREATE TABLE mycatalog.testks.testtab (key Int, value STRING) USING cassandra PARTITIONED BY (key)") 1 2 spark.sql("CREATE DATABASE IF NOT EXISTS mycatalog.testks WITH DBPROPERTIES (class='SimpleStrategy',replication\_factor='1')") spark.sql("CREATE TABLE mycatalog.testks.testtab (key Int, value STRING) USING cassandra PARTITIONED BY (key)") 3. To List the contents Shell spark.sql("SHOW NAMESPACES FROM mycatalog").show spark.sql("SHOW TABLES FROM mycatalog.testks").show 1 2 spark.sql("SHOW NAMESPACES FROM mycatalog").show spark.sql("SHOW TABLES FROM mycatalog.testks").show Creating and Submitting a Scala Job ----------------------------------- In this step of the tutorial we will demonstrate how to build and submit a Scala job. This is useful where you wish to create a job and submit it multiple times. 1. Log in to your Spark client machine. 2. Create required directories for your project: Shell mkdir ~/cassandra-count cd cassandra-count mkdir -p src/main/scala mkdir project 1 2 3 4 mkdir ~/cassandra-count cd cassandra-count mkdir -p src/main/scala mkdir project 3. Create a file called **build.sbt** in the cassandra-count directory with the following contents (note: the blank lines are important): Scala name := "cassandra-count" version := "1.0" scalaVersion := "2.11.8" libraryDependencies += "org.apache.spark" %% "spark-core" % "2.1.1" % "provided" libraryDependencies += "com.datastax.spark" %% "spark-cassandra-connector" % "2.0.2" libraryDependencies += "org.apache.spark" %% "spark-sql" % "2.1.1" % "provided" assemblyMergeStrategy in assembly ~= { (old) => { case PathList("META-INF", "io.netty.versions.properties") => MergeStrategy.last case x => old(x) } } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 name := "cassandra-count" version := "1.0" scalaVersion := "2.11.8" libraryDependencies += "org.apache.spark" %% "spark-core" % "2.1.1" % "provided" libraryDependencies += "com.datastax.spark" %% "spark-cassandra-connector" % "2.0.2" libraryDependencies += "org.apache.spark" %% "spark-sql" % "2.1.1" % "provided" assemblyMergeStrategy in assembly ~= { (old) => { case PathList("META-INF", "io.netty.versions.properties") => MergeStrategy.last case x => old(x) } } 4. Create a file called **assembly.sbt** in the cassandra-count/project directory with the following contents (this will include required dependencies in the output jars): Scala addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.5") 1 addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.5") 5. Create a file called **cassandra-count.scala** in the cassandra-count/src/main/scala directory with the following contents: Scala import org.apache.spark.SparkContext import org.apache.spark.SparkConf import com.datastax.spark.connector.\_ object cassandraCount { def main(args: Array\[String\]) { // 1. Create a conf for the spark context // In this example, spark master and cassandra nodes info are provided in a separate count.conf file. val conf = new SparkConf().setAppName("Counting row of a cassandra table") // 2. Create a spark context val sc = new SparkContext(conf) // 3. Create an rdd that connect to the cassandra table "schema\_keyspaces" of the keyspace "system" val rdd = sc.cassandraTable("system\_schema", "keyspaces") // 4. Count the number of row val num\_row = rdd.count() println("n Number of rows in system\_schema.keyspaces: " + num\_row + "n") // 5. Stop the spark context. sc.stop } } 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 import org.apache.spark.SparkContext import org.apache.spark.SparkConf import com.datastax.spark.connector.\_ object cassandraCount { def main(args: Array\[String\]) { // 1. Create a conf for the spark context // In this example, spark master and cassandra nodes info are provided in a separate count.conf file. val conf = new SparkConf().setAppName("Counting row of a cassandra table") // 2. Create a spark context val sc = new SparkContext(conf) // 3. Create an rdd that connect to the cassandra table "schema\_keyspaces" of the keyspace "system" val rdd = sc.cassandraTable("system\_schema", "keyspaces") // 4. Count the number of row val num\_row = rdd.count() println("n Number of rows in system\_schema.keyspaces: " + num\_row + "n") // 5. Stop the spark context. sc.stop } } 6. Create a file called **cassandra-count.conf** in the cassandra-count directory (this file contains the configuration that will be used when we submit the job): Scala spark.master spark://<spark\_master\_private\_IP1>:7077,<spark\_master\_private\_IP2>:7077,<spark\_master\_private\_IP3>:7077 spark.executor.memory 1g spark.driver.host <your ip> spark.cassandra.connection.host <private ip of cassandra> spark.cassandra.auth.username iccassandra spark.cassandra.auth.password <iccassandra password> spark.serializer org.apache.spark.serializer.KryoSerializer spark.eventLog.enabled true spark.eventLog.dir . 1 2 3 4 5 6 7 8 9 spark.master spark://<spark\_master\_private\_IP1>:7077,<spark\_master\_private\_IP2>:7077,<spark\_master\_private\_IP3>:7077 spark.executor.memory 1g spark.driver.host <your ip> spark.cassandra.connection.host <private ip of cassandra> spark.cassandra.auth.username iccassandra spark.cassandra.auth.password <iccassandra password> spark.serializer org.apache.spark.serializer.KryoSerializer spark.eventLog.enabled true spark.eventLog.dir . 7. Build the job (from cassandra-count directory): Shell sbt assembly 1 sbt assembly 8. Submit the job (from cassandra-count directory): Shell ~/spark-2.1.1-bin-hadoop2.6/bin/spark-submit --properties-file cassandra-count.conf --class cassandraCount target/scala-2.11/cassandra-count-assembly-1.0.jar 1 ~/spark-2.1.1-bin-hadoop2.6/bin/spark-submit --properties-file cassandra-count.conf --class cassandraCount target/scala-2.11/cassandra-count-assembly-1.0.jar 9. You should see a lot of log messages with the row count message about 15 messages from the end.![](https://www.instaclustr.com/wp-content/uploads/2017/09/spark_job_result_pix-768x396.png) Conclusion ---------- In this tutorial you have learned how to: -
