Spark on AWS EMR

Using Spark in AWS EMR with Databand.

By default, DBND uses EMR step to submit Spark jobs to EMR. The command line is going to be generated using SparkSubmitHook, thus airflow connection should be defined to be used by that hook.

Configuring AWS EMR

  1. Set spark_engine to emr
  2. Define cluster ID in EMR configuration:
[emr]
cluster_id= < emr cluster name id >
  1. Define airflow connection:
$airflow connections --delete --conn_id spark_emr
$airflow connections --add \
    --conn_id spark_emr \
    --conn_type docker \
    --conn_host local

Supporting Inline Spark Tasks on EMR

In order to support inline tasks, install the dbnd and dbnd-spark package on your EMR cluster nodes. See Installing DBND on Spark Cluster for more information.
