Jan Van Besien updated HBASE-4844:
----------------------------------
Release Note: Addition of two methods to the WALObserver to be notified of
HLog rotation (postLogRoll) and HLog archiving (postLogArchive).
Status: Patch Available (was: Open)
I created a fairly straightforward patch to add the two discussed methods to
the WALObserver. It simply makes the calls whenever the similar methods in
WALActionListener are also called. It seems to work, but maybe I overlooked
some things I don't know of?
I included a basic test for the postLogRoll method.
> Coprocessor hooks for log rolling

> In order to eventually do point in time recovery we need a way to reliably
> back up the logs. Rather than adding some hard coded changes, we can provide
> coprocessor hooks and folks can implement their own policies.
