Mohammad Arshad commented on HBASE-24212:
-----------------------------------------
Yes it is handled but only in master branch
In Master branch
{code:java}
List<RSGroupInfo> groups = master.getRSGroupInfoManager().listRSGroups();
{code}
In Branch-2
{code:java}
List<RSGroupInfo> groups =
RSGroupTableAccessor.getAllRSGroupInfo(master.getConnection());
{code}
In master branch rsgroup list is read from the memory.
In branch-2 it is scanned from meta table
We should take master branch change in branch-2 also but it causes cyclic
dependency issue.
So we have to first move the rsgroup code to server then we can take master
branch change.
