Duo Zhang commented on HBASE-22695:
-----------------------------------

This will be huge change.

I think we need to define the behavior first. In the old implementation, changing the rsgroup of a table will lead to a move, but changing the rsgroup config of a namespace will not.

In general, I prefer we do not trigger a move when doing this first, including changing the server set of a rsgroup. Let's do this asynchronously. The only exception is changing the rsgroup config of a table, where we need to reopen the regions of a table. Later we could see if  we can provide a synchronous way, maybe we can return a proc id to client to let them query the status, just like what we have done for create table, etc.
