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

@Jimmy
I did not raise any issue to fix that.  So let this JIRA be there to fix this.
bq.HBASE-6881 is just partially fixing this issue, by making the issue happens a little less.
Yes, right

Seeing the HMaster startup code and the RS start up code, retry should be the ideal way. 

Adding a retry logic in the assign code on ServerNotRunningYetException will be it affect
normal regions also?

> In looking into a TestReplication failure, I found out sometimes assignRoot could fail,
for example, RS is not serving traffic yet.  In this case, the master will keep waiting for
root to be available, which could never happen.
>  
> Need to gracefully terminate master if root is not assigned properly.
