Xu Cang updated HBASE-21117:
----------------------------
Description:
When working on HBASE-20666, I found out HBASE-18350 did not get ported to
branch-1, which causes procedure to hang when #moveTables called sometimes.
After looking into the 18350 patch, seems it's important since it fixes 4
issues. This Jira is an attempt to backport it to branch-1.
Edited: Aug26.
After reviewed the HBASE-18350 patch. I decided to only port part 2 of the
patch.
Because part1 and part3 is AMv2 related. I won't touch is since Amv2 is only
for branch-2

Subject: [PATCH] HBASE-18350 RSGroups are broken under AMv2
- Table moving to RSG was buggy, because it left the table unassigned.
Now it is fixed we immediately assign to an appropriate RS
(MoveRegionProcedure).
*- Table was locked while moving, but unassign operation hung, because*
*locked table queues are not scheduled while locked. Fixed. ---- port this
one.*
- ProcedureSyncWait was buggy, because it searched the procId in
executor, but executor does not store the return values of internal
operations (they are stored, but immediately removed by the cleaner).
- list_rsgroups in the shell show also the assigned tables and servers.
