Subject [jira] [Created] (HDFS-3521) Allow namenode to toleration edit log corruption
Date Sat, 09 Jun 2012 01:14:23 GMT
Tsz Wo (Nicholas), SZE created HDFS-3521:

             Summary: Allow namenode to toleration edit log corruption
                 Key: HDFS-3521
                 URL: https://issues.apache.org/jira/browse/HDFS-3521
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: name-node
            Reporter: Tsz Wo (Nicholas), SZE
            Assignee: Tsz Wo (Nicholas), SZE

HDFS-3479 adds checking for edit log corruption. It uses a fixed UNCHECKED_REGION_LENGTH (=PREALLOCATION_LENGTH)
so that the bytes at the end within the length is not checked.  Instead of not checking the
bytes, we should check everything and allow toleration.
