Thomas Graves commented on MAPREDUCE-3889:
------------------------------------------
I'm fine with disabling it for now.
> 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.
