  title: Amazon EMR Launch a Hadoop and Hive Cluster
  summary: Create an EMR cluster with the Hadoop and Hive applications installed.
  description: >-
    Launches a managed Amazon EMR cluster pre-configured for batch SQL and
    MapReduce analytics by installing both the Hadoop and Hive applications.
    The workflow calls RunJobFlow with the supplied cluster name, instance
    configuration, and release label, requests Hadoop and Hive, 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.
