Create a cluster with Apache Spark - Amazon EMR

Create a cluster with Apache Spark

The following procedure creates a cluster with Spark installed using Quick Options in the Amazon EMR console.

You can alternatively use Advanced Options to further customize your cluster setup, or to submit steps to programmatically install applications and then run custom applications. With either cluster creation option, you can choose to use AWS Glue as your Spark SQL metastore. See Use the AWS Glue Data Catalog as the metastore for Spark SQL for more information.

To launch a cluster with Spark installed

  1. Open the Amazon EMR console at https://console.aws.amazon.com/emr.

  2. Choose Create cluster to use Quick Options.

  3. Enter a Cluster name. Your cluster name can't contain the characters <, >, $, |, or ` (backtick).

  4. For Software Configuration, choose a Release option.

  5. For Applications, choose the Spark application bundle.

  6. Select other options as necessary and then choose Create cluster.

    Note

    To configure Spark when you are creating the cluster, see Configure Spark.

To launch a cluster with Spark installed using the AWS CLI

  • Create the cluster with the following command.

    aws emr create-cluster --name "Spark cluster" --release-label emr-7.4.0 --applications Name=Spark \
--ec2-attributes KeyName=myKey --instance-type m5.xlarge --instance-count 3 --use-default-roles
Note

Linux line continuation characters (\) are included for readability. They can be removed or used in Linux commands. For Windows, remove them or replace with a caret (^).

To launch a cluster with Spark installed using the SDK for Java

Specify Spark as an application with SupportedProductConfig used in RunJobFlowRequest.

  • The following example shows how to create a cluster with Spark using Java.
