Sean Busbey commented on HBASE-15984:

Since we're talking about data loss, I originally wanted to push this for all 
branches. I'm fine leaving out the metrics additions on maintenance release 
lines if folks prefer, but I've always interpreted the operational section of 
the compatibility promises as saying we wouldn't remove metrics in a 
maintenance release rather than that we wouldn't add them.

> Given failure to parse a given WAL that was closed cleanly, replay the WAL.
