-------------------------------------
@Stack
What about we define the safemode for master like namenode, where master is
aborting and initializing.
In the safemode, we maybe could also refuse ServerShutdownHandler which
simplify solution of HBASE-5270.

> In our testing environment,
> When master is initializing, we found conflict problems between
> master#assignAllUserRegions and EnableTable event, causing assigning region
> throw exception so that master abort itself.
> We think we'd better refuse operations from Admin, such as CreateTable,
> EnableTable,etc, It could reduce error.
