Michael Stack created HBASE-23280:
-------------------------------------
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].
