  title: Amazon EMR Run a Spark ETL Job
  summary: Launch a Spark cluster and queue an ETL processing step in one call.
  description: >-
    Launches a managed Amazon EMR cluster with Apache Spark installed and
    submits the supplied ETL processing steps in the same RunJobFlow call, so an
    extract-transform-load workload begins as soon as the cluster is
    provisioned. The workflow passes through the caller supplied name, instance
    configuration, release label, and steps, requests the Spark application, and
    returns the new cluster's JobFlowId. Every step spells out its request
    inline, including the AWS JSON protocol X-Amz-Target header, so the flow can
    be read and executed without opening the underlying OpenAPI description.
