             Summary: Spark on Kubernetes - basic submission client
                 Key: SPARK-22646
                 URL: https://issues.apache.org/jira/browse/SPARK-22646
             Project: Spark
          Issue Type: Sub-task
          Components: Scheduler
    Affects Versions: 2.3.0
            Reporter: Anirudh Ramanathan


The submission client is mainly responsible for creating the Kubernetes pod 
that runs the Spark driver. It follows a step-based approach to construct the 
driver pod, as the code under the submit.steps package shows. The steps are 
orchestrated by DriverConfigurationStepsOrchestrator. Client creates the driver 
pod and waits for the application to complete if it's configured to do so, 
which is the case by default.

This PR also contains Dockerfiles of the driver and executor images. They are 
included because some of the environment variables set in the code would not 
make sense without referring to the Dockerfiles.
