Duo Zhang commented on HBASE-15481:
-----------------------------------
I agree with [~busbey] that we may have a WAL which does not rely a FileSystem
in the future so it is not a good idea to expose a 'Path' parameter in
coprocessor because it could be used outside out control.
I think you could use {{WALActionsListener}} for now since it is controlled by
us although [~stack] has said many times he want to kill that stuff :)
> Add pre/post roll to WALObserver

> have a pre/post Roll too.
