             Summary: Implement FLIP-6 YARN client
                 Key: FLINK-4931
                 URL: https://issues.apache.org/jira/browse/FLINK-4931
             Project: Flink
          Issue Type: Sub-task
          Components: YARN
         Environment: {{flip-6}} feature branch
            Reporter: Stephan Ewen


The FLIP-6 YARN client can follow parts of the existing YARN client.

The main difference is that it does not wait for the cluster to be fully 
started and for all TaskManagers to register. It simply submits 

  - Set up all configurations and environment variables
  - Set up the resources: Flink jar, utility jars (logging), user jar
  - Set up attached tokens / certificates
  - Submit the Yarn application
  - Listen for leader / attempt to connect to the JobManager to subscribe to 
updates
  - Integration with the Flink CLI (command line interface)
