Without a backport of HBASE-10569, which I don't think we can backport to a stable branch, meta updates after this patch is applied in the current state would happen via a remote RPC call in a synchronized block as per my understanding, which won't be ok. Also, on any minor upgrade e.g. 0.98.4 to 0.98.5, it should be possible to do a rolling restart from .4 to .5. This change would seems to require *two* rolling restarts, and on the second restart the ordering of the master restart will be important. Let's take a step back. Why is this change needed in 0.98? was (Author: apurtell): This seems like a big change to attempt to backport to a stable branch.
