Jeffrey Zhong updated HBASE-7824:
---------------------------------
Attachment: hbase-7824.patch
Unblock master starts up when there are non-meta region servers' split work.
After the fix, master will only block by meta region server log spliting work.
More details as following:
1) Adding support to fast master up
2) Adding a test case for new code
3) Fix test function makehlog to creat rows with keys within assigned
region's key space
> Improve master start up time when there is log split 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.
