----------------------------------------

             Summary: LocalJobRunner does not work on Windows.
                 Key: MAPREDUCE-5470
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5470
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 3.0.0, 2.1.1-beta
            Reporter: Chris Nauroth


{{LocalJobRunner#getLocalTaskDir}} creates a directory that is unique to the 
task ID.  The logic of this method concatenates the local job dir and a 
task-specific path, but one of the arguments is a {{Path}} with a scheme, so 
the final result has "file:" embedded in it.  This works on Linux, but the ':' 
is an invalid character in a file name on Windows.
