--------------------------------------------------------------
Thanks [~sunilg] for reviewing.
1. The existing sched-conf cli call fails on unsecure Cluster when
AuthenticationFilterInitializer configured with "Unable to get user.name", it
is a bug in existing code which is fixed as part of this. It does not break
existing behavior.
2. Concurrent writes are possible and it will fail if format happens without
reinitialize. Have added a formatLock which makes writes to wait for completion
of any parallel format & reinitialize and vice versa.
Have attached [^YARN-9864-005.patch] fixing the review comment 2. Thanks.
