             Summary: Document that region replica does not work well with AMv2
                 Key: HBASE-20830
                 URL: https://issues.apache.org/jira/browse/HBASE-20830
             Project: HBase
          Issue Type: Sub-task
            Reporter: Duo Zhang


As we can see lots of TODOs for region replica feature in the AssignmentManager' code. And also, now we rely on the openSeqNum to determine whether a region has been successfully reopened, but the openSeqNum for a non-default replica region seems unstable...

It is too late for the 2.1.0 release so let's just add a note in ref guide to say that region replica does not work well with AMv2 first, and then start to make it stable in follow on minor or major release lines.
