[jira] [Created] (HBASE-23006) RSGroupBasedLoadBalancer should also try to place replicas for the same region to different region servers

Duo Zhang created HBASE-23006:
---------------------------------

             Summary: RSGroupBasedLoadBalancer should also try to place replicas for the same region to different region servers
                 Key: HBASE-23006
                 URL: https://issues.apache.org/jira/browse/HBASE-23006
             Project: HBase
          Issue Type: Bug
          Components: Region Assignment, rsgroup
            Reporter: Duo Zhang


Found this when implementing HBASE-22971. TestSCPWithReplicas fails when RSGroupBasedLoadBalancer is enabled.

And this can be reproduced by a UT on master branch too. I think the problem is that in RSGroupBasedLoadBalancer.retainAssignment we do not consider region replicas.

We should fix this.
