             Summary: Purge rep_barrier:seqnumDuringOpen on delete of Region
                 Key: HBASE-23280
                 URL: https://issues.apache.org/jira/browse/HBASE-23280
             Project: HBase
          Issue Type: Bug
          Components: Replication
            Reporter: Michael Stack


The Region GC Procedure only cleans the 'info' column family.  We also write a rep_barrier column family as of HBASE-20115 . HBASE-20117 adds a chore to clean them up after-the-fact.  I've not studied how rep_barrier works (There is a comment in MetaTableAccessor to add explaination).

This issue is about adding the deletion of the rep_barrier content on region delete ([~zhangduo] will this mess up serial replication?).

I want to clean out these rows. They occasionally can be misinterpreted in such as the hbck report or in simple loading tools, we'll find the rep_barrier row and then fail because no accompanying info:regioninfo.

Perhaps removing rep_barrier column family promptly is the wrong thing to do... we need the lag for replication to catch up.... Let me know [~zhangduo].
