Sean Busbey commented on HBASE-15481:
-------------------------------------
I think the problem with exposing this in the coprocessor interfaces is that it ties us to
a FS Path, which we weren't before. At a minimum, there should be some kind of boolean a coprocessor
can check in the WALCoprocessorEnvironment that lets them know if {{WAL}}s have corresponding
{{Path}}s and thus the coprocessor can expect these methods to be called.
> Add pre/post roll to WALObserver

Roll too.
