[jira] [Created] (HDFS-2174) Complete decoupling of failure states between edits and image dirs

Complete decoupling of failure states between edits and image dirs
------------------------------------------------------------------

                 Key: HDFS-2174
                 URL: https://issues.apache.org/jira/browse/HDFS-2174
             Project: Hadoop HDFS
          Issue Type: Sub-task
          Components: name-node
    Affects Versions: 0.23.0
            Reporter: Todd Lipcon


After HDFS-1073, there is no reason to couple the failure state of edits dirs and image dirs. However, there is still a small amount of coupling in that image dirs are restored only when edits are rolled. This is not problematic, and mirrors the old behavior, but we could do better now -- eg provide an interfaces for ops to monitor and manually manage image dir states at any point in time.

This is targeted to be fixed _after_ HDFS-1073 is merged.
