Jeffrey Zhong commented on HBASE-7824:
--------------------------------------
Yep, I've taken care of that. Basically, synchronized log split tasks before
SSH is enabled. Once you agree the approach in general, I'll submit the
modified patch for review.
A question through: Should we do expireServer firstly and then do log splitting
after we have the log splitting synchronization mechanism before SSH is enabled.
> 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.
