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

             Summary: PATH environment variable contains duplicate values in 
map and reduce tasks on Windows.
                 Key: MAPREDUCE-5850
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5850
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: client
    Affects Versions: 3.0.0, 2.4.0
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth
            Priority: Minor


The value of the PATH environment variable gets appended twice before execution 
of a container for a map or reduce task.  This is ultimately harmless at 
runtime, but it does cause a failure in {{TestMiniMRChildTask}} when running on 
Windows.
