             Summary: Allow DistributedShell to take a placement specification for containers it wants to launch
                 Key: YARN-7745
                 URL: https://issues.apache.org/jira/browse/YARN-7745
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Arun Suresh
            Assignee: Arun Suresh


This is add a '-placement_spec' option to the distributed shell client. Where the user can specify a string-ified specification for how it wants containers to be placed.

For eg:
{noformat}
$ yarn org.apache.hadoop.yarn.applications.distributedshell.Client –jar \
$YARN_DS/hadoop-yarn-applications-distributedshell-$YARN_VERSION.jar \
 -shell_command sleep -shell_args 10 -placement_spec <placementspecification>
{noformat}
