------------------------------------------------------------

I saw another situation that may cause random assignment. When we restart hbase, if we start
master first, and then region servers.
Once one region server count in, master will start to begin region assignment. There is a
possibility that the assign plan is created for a region before its last region server up,
so AM will randomly chose one region servers for this region. 

And if we restart all rs before master, we will not see above issues.
