Jeffrey Zhong updated HBASE-7824:
---------------------------------
Release Note: Master now won't wait for existing or previously left log
splitting work(except for ROOT and META region servers) finish before it can
start up. Sometimes log splitting work could take more than minuets. In normal
case, master node starts much faster than before when there is region server
recovery work going on. The feature can be disabled by set configuration value
""hbase.master.wait.for.log.splitting" to true.(default value is false)
> 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.
