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

             Summary: RM should optionally not kill all containers when an 
ApplicationMaster exits
                 Key: YARN-1490
                 URL: https://issues.apache.org/jira/browse/YARN-1490
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Vinod Kumar Vavilapalli
            Assignee: Vinod Kumar Vavilapalli


This is needed to enable work-preserving AM restart. Some apps can chose to 
reconnect with old running containers, some may not want to. This should be an 
option.
