regions are going to be assigned to one same region server.
Key: HBASE-25158
URL: https://issues.apache.org/jira/browse/HBASE-25158
Project: HBase
Issue Type: Sub-task
Reporter: Huaxiang Sun
Region replica has enhancement in balancer that primary region and its replicas
are not going to be assigned to the same region server. Today, there is only
one meta region, so this enhancement is still enough. With split meta coming
in, it needs to make sure that no meta regoin/replicas is going to be assigned
to the same region server in order to avoid hotspot issue.
