-----------------------------------------------
@Stack,
I am planning to implement the same logic that happens in timeoutmonitor when
it finds a node in OPENING.
->The existing logic takes care of checking if the node had got changed to
OPENED or not. If not forces the node to OFFLINE and again starts assignment.
So we can also do the same here.
Also as per the current changes that am trying out in
timeoutmonitor(HBASE-4015) this change can also be incorporated. Or do you want
me to submit a seperate patch for this?
> While master restarts and if the META region's state is OPENING then master
> cannot assign META until timeout monitor deducts

> Priority: Minor
>
> 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
