> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: resourcemanager
> Affects Versions: 2.2.0
> Reporter: Karthik Kambatla
> Assignee: Karthik Kambatla
> Priority: Blocker
> Fix For: 2.3.0

>
> YARN-891 augments the RMStateStore to store information on completed
> applications. In the process, it adds transitions from NEW to FINAL_SAVING.
> This leads to the RM trying to update entries in the state-store that do not
> exist. On ZKRMStateStore, this leads to the RM crashing.
> Previous description:
> ZKRMStateStore fails to handle updates to znodes that don't exist. For
> instance, this can happen when an app transitions from NEW to FINAL_SAVING.
> In these cases, the store should create the missing znode and handle the
> update.
