Wangda Tan updated YARN-3410:
-----------------------------
Summary: YARN admin should be able to remove individual application records
from RMStateStore (was: YARN admin should be able to remove individual
application record from RMStateStore)
> 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: Bug
> Components: resourcemanager, yarn
> Reporter: Wangda Tan
> 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.
