Subject [jira] [Commented] (HBASE-13811) Splitting WALs, we are filtering out too many edits -> DATALOSS

Pardon me, I don't see the problem here?
{quote}
Not a big problem... The only thing is I do not like java.lang.Long...I can prepare a patch
to explain how to implement it.

What do you mean by 'startCacheFlush is restricted'.
{quote}
'startCacheFlush' is a exact name which tell us what it will do and I think people will only
call it when they want to flush a region, so it is less hurt to change its behavior. 'getEarliestMemstoreSeqNum'
 is a more general name, people can use it everywhere when they want to get the value.

> 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.
