Jean-Daniel Cryans commented on HBASE-6758:
-------------------------------------------

Ah I see, I didn't fully grok the new preRoll/postRoll dance in my first 
review. That's clever.

My one last concern before committing would be what happens when we are able to 
compute a new HLog name and put it up in ZK, but then fail to create the HLog 
and the RS dies. Will the recovered queue hang or will it abandon that HLog? 
FWIW there's another jira regarding that problem but this could be a new 
failure case.

> I have seen cases where the replication-executor would lose data to replicate 
> since the file hasn't been closed yet. Upon closing, the new data becomes 
> visible. Before that happens the ZK node shouldn't be deleted in 
> ReplicationSourceManager.logPositionAndCleanOldLogs. Changes need to be made 
> in ReplicationSource.processEndOfFile as well (currentPath related).
