Subject [jira] [Created] (HDFS-5287) JN need not validate finalized log segments in newEpoch
Date Tue, 01 Oct 2013 17:39:24 GMT
Todd Lipcon created HDFS-5287:
---------------------------------

             Summary: JN need not validate finalized log segments in newEpoch
                 Key: HDFS-5287
                 URL: https://issues.apache.org/jira/browse/HDFS-5287
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: qjm
    Affects Versions: 2.1.1-beta
            Reporter: Todd Lipcon
            Priority: Minor


In {{scanStorageForLatestEdits}}, the JN will call {{validateLog}} on the last log segment,
regardless of whether it is finalized. If it's finalized, then this is a needless pass over
the logs which can adversely affect failover time for a graceful failover.
