----------------------------------

             Summary: add container_tag to Distributedshell's env
                 Key: YARN-5696
                 URL: https://issues.apache.org/jira/browse/YARN-5696
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: applications/distributed-shell
            Reporter: kyungwan nam
            Assignee: kyungwan nam
            Priority: Minor


a number of containers can be allocated by "num_containers" option.
but, there is no way to assign different input to each container.

each container has a unique id between 0 and (num_containers - 1).
so, user can assign different input (or role) per container.
