> 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.
