----------------------------------------------
discussed offline with [~zyork], provided the port to branch-2, built and
tested (see [PR#88|https://github.com/apache/hbase/pull/88]) and tried
cherry-pick on branch-2.0 and branch-2.1.

> Courtesy of [~elserj], I learn that changing WAL we need to set two places...
> both hbase.wal.meta_provider and hbase.wal.provider. Operator should only
> have to set it in one place; hbase.wal.meta_provider should pick up general
> setting unless hbase.wal.meta_provider is explicitly set.
