should be independent of log aggregation
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.
