stack commented on HBASE-20856:
-------------------------------
Nice fix. Thanks [~taklwu].
+1 for branch-2.0 ([~Apache9] you good for branch-2.1?).
Thanks for the pointer [~busbey] into compat guidelines. I think this change
worth bending the rules for. This patch makes it so WAL fs config is what
operators would expect whereas what was there previous would have them baffled.
Let me add a note to this effect up in the RN.

> 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.
