chunhui shen commented on HBASE-7824:
-------------------------------------
bq.So the open will fail even if META region can be opened but no one can
access it because root is offline
We will retry if fail to update META location in ROOT RS.
Root will be online finally, however Meta region won't be re-assigned.
> Improve master start up time when there is log splitting work

> When there is log split work going on, master start up waits till all log
> split work completes even though the log split has nothing to do with meta
> region servers.
> It's a bad behavior considering a master node can run when log split is
> happening while its start up is blocking by log split work.
> Since master is kind of single point of failure, we should start it ASAP.
