Andrew Purtell updated HBASE-2059:
----------------------------------

   Status: Patch Available  (was: Open)

Passes all local tests, importantly:
* TestFullLogReconstruction
* TestHLog

I'd like to see this go in. It's the foundation for a bake off between different log formats, for example, SequenceFile vs. Avro's DataFileWriter.

I'll add hbase-default.xml entries on commit as J-D suggests.

Break out WAL reader and writer impl from HLog

Use Configuration and reflection to bind HLog reader and writer at runtime, to allow users to chose between different HLog reader/ writer implementation pairs.
