------------------------------
For state store format in YARN-2131, discussion happened whether to format
state using admin service or resourcemanager start up options [comment

Similarly I am thinking for application state deletion options
# ./yarn resourcemanager -delete-from-state-store app-id OR
# ./yarn rmadmin -delete-from-state-store app-id
1st choice is pretty staight forward deletion neverthless of app state is
finished or running. I would like to choose 2nd option.
> YARN admin should be able to remove individual application records from

> 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.
