> I've been running ITBLLs against branch-1 around HBASE-13616 (move of ServerShutdownHandler
to pv2). I have come across an instance of dataloss. My patch for HBASE-13616 was in place
so can only think it the cause (but cannot see how). When we split the logs, we are skipping
legit edits. Digging.
