> 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
