Wellington Chevreuil commented on HBASE-29083:
----------------------------------------------
So if we want to switch the state, we need to change the property and perform a
restart? Do clusters participating on a "read replica" group know about each
other? How can we validate that no more than one participating cluster is in
non-readonly mode?
