Release Note:

Hide
The regionserver carrying .META. / -ROOT- region will now write two WALs; the usual one w/ all edits and then a special one with a .meta. suffix into which all edits for .META. / -ROOT- region go. These files will be recovered first on server crash. This feature is turned OFF by default. The configuration hbase.regionserver.separate.hlog.for.meta must be set to true to enable this behavior.

Description

I am interested in backporting ~~HBASE-7213~~ to 0.94. Helps to address more of the MTTR story. Offline discussion with Lars indicated he is interested as well.
