Jonathan Hsieh commented on HBASE-6573:
---------------------------------------
An update here -- I've been working on making this code significantly more
straightforward, and hopefully will be posting some patches related to this
soon.
I'm going to post a few slides, explaining what the classes are, and how they
are related and used. The first patch cut will be off of an old branch -- I'll
port this to the snapshot branch after I get the one of the online snapshot
implementations working again. At the end of the day, this will have removed
a few layers, most of the generics, and renamed/restructured quite a bit.
