Elliott Clark commented on HBASE-7965:
--------------------------------------
bq.What is the rolling upgrade story (0.94.5 -> 0.94.7). Does cause any
incompatibilities?
At some point the master will be a version that expects the locks to be
honored. The region servers will be in some indeterminate state.
> Port table locking to 0.94 (HBASE-7305, HBASE-7546, HBASE-7933)

> Port table locking to 0.94 (HBASE-7305, HBASE-7546, HBASE-7933). This is a
> new feature, but there has been some interest, and it is necessary for
> snapshots, and online merge, which are also candidates for backport.
> If we port snapshots, we might need HBASE-7848 as well.
> We can also do disabled by default.
