          • Type: Improvement
          • Status: Closed
          • Priority: Critical
          • Resolution: Fixed

          • Fix Version/s: 0.95.0

            Reviewed
          • Release Note:
            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.

            Description

            Over on HBASE-6774, there is a discussion on separating out the edits for .META. regions from the other regions' edits w.r.t where the edits are written. This jira is to track an implementation of that.
