Robert Kanter commented on YARN-2131:
-------------------------------------
Ya, this would be offline. We were thinking of something similar to the {{hdfs
namenode -format}} command for formatting the NN. Something like {{yarn
resourcemanager -format}} that would wipe out whichever RM state store you had
configured (i.e. delete all znodes in ZKRMStateStore or delete all files in
FileSystemRMStateStore)
> Add a way to nuke the RMStateStore

> Key: YARN-2131
> URL: https://issues.apache.org/jira/browse/YARN-2131
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 2.4.0
> Reporter: Karthik Kambatla
> Assignee: Robert Kanter
>
> There are cases when we don't want to recover past applications, but recover
> applications going forward. To do this, one has to clear the store. Today,
> there is no easy way to do this and users should understand how each store
> works.
