[jira] [Created] (MAPREDUCE-4872) MapReduce JVM launch does not use correct working directory on Windows

Chris Nauroth created MAPREDUCE-4872:
----------------------------------------

             Summary: MapReduce JVM launch does not use correct working directory on Windows
                 Key: MAPREDUCE-4872
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4872
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: client
            Reporter: Chris Nauroth
            Assignee: Chris Nauroth
             Fix For: trunk-win


{{MapReduceChildJVM#getVMCommand}} sets java.io.tmpdir by using environment variable PWD as the root of the path.  On Windows, %PWD% likely will not be defined.  Instead, we need to use %CD%.  Any part of the codebase that uses {{Environment#PWD}} is likely to be impacted by this.
