-----------------------------------------------
@Chunhui
Idea is good.
But do we need
{code}
boolean waitUntilNoRegionsInTransition(final long timeout)
{code}
such wait mechanisms? Also can we have a configuration like how we have in the
master start up to ensure whether to use roundRobin or not.
Because if i have a custom load balancer i will get a call back in this case
for round robin. May be we can avoid that if we have the configuration? What
do you feel Chunhui?

> 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.
