------------------------------------
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.
