Bharath Vissapragada commented on HBASE-22982:
----------------------------------------------
Backported to branch-1 with a caveat: GracefulRollingRestartRsAction was
omitted due to a dependency on RegionMover class which itself is a significant
chunk of backport. I was more interested in having the SUSPEND/RESUME
operations available.
> Send SIGSTOP to hang or SIGCONT to resume rs and add graceful rolling restart
