Sean Busbey commented on HBASE-15481: ------------------------------------- I'd also love to kill WALActionListener. The problem with it here is that you can't say "I want to listen to all wals". You'd effectively have to first make a coprocessor that was notified of every wal somehow (I guess WALObserver and track what comes in on writes?) and then register yourself as a listener on each. It's terrible and I don't really have a better solution for now, which is why I'm -0 rather than -1. > Add pre/post roll to WALObserver > -------------------------------- > > Key: HBASE-15481 > URL: https://issues.apache.org/jira/browse/HBASE-15481 > Project: HBase > Issue Type: New Feature > Affects Versions: 1.3.0 > Reporter: Matteo Bertozzi > Assignee: Matteo Bertozzi > Priority: Trivial > Fix For: 2.0.0, 1.3.0 > > Attachments: HBASE-15481-v0.patch, HBASE-15481-v1.patch, > HBASE-15481-v1.patch > > > currently the WALObserver has only a pre/post Write.
