             Summary: Windows CMD processor doesn't use double quotes
                 Key: MAPREDUCE-4601
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4601
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 1-win
            Reporter: Owen O'Malley
            Assignee: Owen O'Malley


Currently, the task launch script under windows matches Linux and double quotes all of the values. Unfortunately, the Windows' CMD processor doesn't need and doesn't ignore the double quotes. The main symptom of this is that the CLASSPATH loses the first and last entries.

{code}
set CLASSPATH="c:\foo;c:\bar;c:\baz"
{code}

results in having '"c:\foo' 'c:\bar' and 'c:\baz"' on the classpath. Of those three, only the 'c:\bar' is valid.
