Amareshwari Sriramadasu resolved MAPREDUCE-2056.
------------------------------------------------

    Resolution: Invalid

Your command should be
$ hadoop jar mapreduce.jar -libjars thirdPartyJar.jar input output
And Main class in mapreduce.jar should implement Tool interface. This usage is 
introduced in HADOOP-3417.

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>    Affects Versions: 0.20.2
>            Reporter: Ron Bodkin
>
> HADOOP-1622 was apparently broken in refactoring (I think in the refactoring 
> that removed JobShell) a few releases ago. e.g., running
> hadoop -libjars lib.jar main.jar Class 
> now tries to run -libjars as a library.
> It would be nice to fix this regression.
