> (Couldn't find another dedicated jira, so creating new one).
> Uploaded patch which is moving ~60 files to the new module. Few notes:
> - The classes remaining in hbase-server are the ones which are intensively coupled with
visibility labels/wal/filesystem/hfile. These can not be migrated to new module until corresponding
subcomponents are untangled out of hbase-server into their own separate modules.
> - Almost all mapreduce tests uses HBaseTestingUtil, so they can't be moved to hbase-mapreduce
module. Given these dependency constraints, one way would be having a separate module for
tests:
> hbase-mapreduce <---- hbase-server <------- hbase-mapreduce-tests 
> Imo, this makes sense and looks fine.
> The only issue is - yetus' pre-commit. It won't run tests in hbase-mapreduce-tests module
if something changed in just hbase-mapreduce. However, yetus' limitation shouldn't warrant
against the idea.
> So i'd say that we should go that way, unless there are better suggestions.
