[jira] [Created] (YARN-8523) Interactive docker shell

Eric Yang created YARN-8523:
-------------------------------

             Summary: Interactive docker shell
                 Key: YARN-8523
                 URL: https://issues.apache.org/jira/browse/YARN-8523
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Eric Yang


Some application might require interactive unix commands executions to carry out operations.  Container-executor can interface with docker exec to debug or analyze docker containers while the application is running.  It would be nice to support an API to invoke docker exec to perform unix commands and report back the output to application master.  Application master can distribute and aggregate execution of the commands to record in application master log file.
