Subject [jira] [Created] (YARN-4325) purge app state from NM state-store should be independent of log aggregation
Date Mon, 02 Nov 2015 18:57:27 GMT
Junping Du created YARN-4325:
--------------------------------

             Summary: purge app state from NM state-store should be independent of log aggregation
                 Key: YARN-4325
                 URL: https://issues.apache.org/jira/browse/YARN-4325
             Project: Hadoop YARN
          Issue Type: Bug
    Affects Versions: 2.6.0
            Reporter: Junping Du
            Assignee: Junping Du
            Priority: Critical


>From a long running cluster, we found tens of thousands of stale apps still be recovered
in NM restart recovery. The reason is some wrong configuration setting to log aggregation
so the end of log aggregation events are not received so stale apps are not purged properly.
We should make sure the removal of app state to be independent of log aggregation life cycle.
