    Details

    • Type: Improvement
    • Status: Closed
    • Priority: Critical
    • Resolution: Fixed
    • Affects Version/s: None
    • Fix Version/s: 0.95.0
    • Component/s: master, regionserver
    • Labels:

    • Hadoop Flags:
      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.
