-----------------------------------------------
@Chunhui
Yes, in SSH case retain assignment is not valid. But what if i don't need the
roundrobin assignment itself to be called like how we have in master startup? I
just meant a similar configuration like the
'hbase.master.startup.retainassign', for eg.,
'hbase.master.servershutdown.roundrobinassign'something like this. Just my
thoughts.

> In the process of ServerShutdownHandler, we currently assign regions singly.
> In the large cluster, one regionserver always carried many regions, this
> action is quite slow.
> What about using bulk assign regions like cluster start up.
> In current logic, if we failed assigning many regions to one destination
> server, we will wait unitl timeout,
> however in the process of ServerShutdownHandler, we should retry it to
> another server.
