TT successfully localizes a task even though the corresponding cache-file has already changed
on DFS.
-----------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-1225
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1225
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: tasktracker
    Affects Versions: 0.21.0
            Reporter: Vinod K V
             Fix For: 0.21.0


This happens with the first task of a job being localized on this TT. TT doesn't check if
the file on DFS is fresh according to the timestamps set in job-conf during submission. After
the first task incorrectly gets localized, all further tasks fail on this TT as expected.

Found this issue while trying to improve test-case for MAPREUCE-913.
