Wangda Tan commented on YARN-3410:
----------------------------------
bq. I think there is choice between start up option vs admin support. If both
are in sync, then it would be better.
Sorry I may not understand, this (remove individual application records) should
be a command line running before RM get started. Could you elaborate this?
> YARN admin should be able to remove individual application records from
> RMStateStore

> Key: YARN-3410
> URL: https://issues.apache.org/jira/browse/YARN-3410
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: resourcemanager, yarn
> Reporter: Wangda Tan
> Assignee: Rohith
> Priority: Critical
>
> When RM state store entered an unexpected state, one example is YARN-2340,
> when an attempt is not in final state but app already completed, RM can never
> get up unless format RMStateStore.
> I think we should support remove individual application records from
> RMStateStore to unblock RM admin make choice of either waiting for a fix or
> format state store.
> In addition, RM should be able to report all fatal errors (which will
> shutdown RM) when doing app recovery, this can save admin some time to remove
> apps in bad state.
