Subject [jira] [Created] (HDFS-6041) Downgrade/Finalize should rename the rollback image instead of purging it
Date Mon, 03 Mar 2014 20:02:21 GMT
Jing Zhao created HDFS-6041:
-------------------------------

             Summary: Downgrade/Finalize should rename the rollback image instead of purging
it
                 Key: HDFS-6041
                 URL: https://issues.apache.org/jira/browse/HDFS-6041
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Jing Zhao
            Assignee: Jing Zhao


After we do rollingupgrade downgrade/finalize, instead of purging the rollback image, we'd
better rename it back to normal image, since the rollback image can be the most recent checkpoint.
