Jean-Daniel Cryans commented on HBASE-4853: ------------------------------------------- TestReplication was :) but it's not its main purpose. It might be doing too much. > HBASE-4789 does overzealous pruning of seqids > --------------------------------------------- > > Key: HBASE-4853 > URL: https://issues.apache.org/jira/browse/HBASE-4853 > Project: HBase > Issue Type: Bug > Reporter: stack > Priority: Critical > Attachments: 4853.txt > > > Working w/ J-D on failing replication test turned up hole in seqids made by > the patch over in hbase-4789.
