> 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.
