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.
