> Sometimes, the RM fails to recover an application. It could be because of
> turning security on, token expiry, or issues connecting to HDFS etc. The
> causes could be classified into (1) transient, (2) specific to one
> application, and (3) permanent and apply to multiple (all) applications.
> Today, the RM fails to transition to Active and ends up in STOPPED state and
> can never be transitioned to Active again.
> The initial stacktrace reported is at
