> HBASE-10378 hides the filesystem from the write-to-the-wal path, but leaves in place the original recovery code. Refactor to remove this leak.
> * Master should have means to say "regions from these servers need recovery"
> * Splitting work should be phrased in terms of region groups and regions from a server instead of files.
> * RegionServers doing recovery should be able to say "please replay the edits from this region"
> * Similarly Replication should be asking for replay of edits as data is aged out of the wal rather than looking specifically at file archiving.
