Matteo Bertozzi commented on HBASE-15481:
-----------------------------------------

I want the "log I rolled". being able to see where it is, keeping a reference, 
making a copy. 
all the stuff that are useful for backup, replication or even just external 
monitoring. 



> Add pre/post roll to WALObserver
