> 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.
