[jira] [Created] (YARN-2182) Update ContainerId#toString() to avoid conflicts before and after RM restart

Tsuyoshi OZAWA created YARN-2182:
------------------------------------

             Summary: Update ContainerId#toString() to avoid conflicts before and after RM restart
                 Key: YARN-2182
                 URL: https://issues.apache.org/jira/browse/YARN-2182
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Tsuyoshi OZAWA
            Assignee: Tsuyoshi OZAWA


ContainerId#toString() doesn't include any information about current cluster id. This leads conflict between container ids. We can avoid the conflicts without breaking backward compatibility by using epoch introduced on YARN-2052.
