Mikhail Antonov commented on HBASE-15068:
-----------------------------------------
Didn't test patch myself on cluster, but looks good to me. +1 for v3.
(For now we don't need any synchronization around these 2 counters in HMaster,
but I kind of suspect we might need in future when running concurrent plans)
