job client tries to use /tasklog interface, but that doesn't exist anymore
--------------------------------------------------------------------------

                 Key: MAPREDUCE-3889
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3889
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.23.1
            Reporter: Thomas Graves
            Priority: Critical


if you specify  -Dmapreduce.client.output.filter=SUCCEEDED option when running a job it tries
to fetch task logs to print out on the client side from a url like: http://nodemanager:8080/tasklog?plaintext=true&attemptid=attempt_1329857083014_0003_r_000000_0&filter=stdout

It always errors on this request with: Required param job, map and reduce

We saw this error when using distcp and the distcp failed. I'm not sure if it is mandatory
for distcp or just informational purposes.  I'm guessing the latter.
