ramkrishna.s.vasudevan updated HBASE-4203:
------------------------------------------
Description:
1. Start Master and 2 RS.
2. If any exception happens while opening the META region the state in znode
will be OPENING.
3. If at this point the master restarts then the master will start processing
the regions in RIT.
4. If the znode is found to be in OPENING then master waits for timeout monitor
to deduct and then call opening.
5. If default timeout monitor is configured(1800000 sec/30 min) then it will
take 30 mins to open the META region itself.
Soln:
====
Better not to wait for the Timeout monitor period to open catalog tables on
Master restart
