Jimmy Xiang commented on HBASE-6381:
------------------------------------

If RS that was online dies during rebuildUserRegions, SSH will take care of it. 
 In the scenario I described, it is like this: master dies, then rs dies,
then rs starts up, then master fails over/starts up.  Now during 
rebuildUserRegions, the rs is online but gets no region assigned.  I think we 
should check if a rs is online, and the regions are opened on the rs too.
                
> AssignmentManager should use the same logic for clean startup and failover

> Currently AssignmentManager handles clean startup and failover very 
> differently.
> Different logic is mingled together so it is hard to find out which is for 
> which.
> We should clean it up and share the same logic so that AssignmentManager 
> handles
> both cases the same way.  This way, the code will much easier to understand 
> and
> maintain.
