Subject [jira] Created: (HDFS-1497) Write pipeline sequence numbers should be sequential with no skips or duplicates
Date Fri, 12 Nov 2010 19:11:15 GMT
Write pipeline sequence numbers should be sequential with no skips or duplicates
--------------------------------------------------------------------------------

                 Key: HDFS-1497
                 URL: https://issues.apache.org/jira/browse/HDFS-1497
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs client
    Affects Versions: 0.20-append, 0.22.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


In HDFS-895 we discovered that multiple hflush() calls in a row without intervening writes
could cause a skip in sequence number. This doesn't seem to have any direct consequences,
but we should maintain and assert the invariant that sequence numbers have no gaps or duplicates.
