chmod in ant package target fails
---------------------------------

                 Key: HADOOP-2271
                 URL: https://issues.apache.org/jira/browse/HADOOP-2271
             Project: Hadoop
          Issue Type: Bug
          Components: build
    Affects Versions: 0.15.0
            Reporter: Adrian Woodhead


If you checkout the trunk to a folder long than /tmp (in my case it is 
"/home/adrian/workspace/hadoop-trunk") and you execute the command:

ant clean package

You get the following error:

BUILD FAILED
/home/adrian/workspace/hadoop-trunk/build.xml:730: Execute failed: 
java.io.IOException: Cannot run program "chmod": java.io.IOException: error=7, 
Argument list too long

I also tried this from the folder "/tmp/trunk" and the package target worked 
fine so I imagine the argument list is becoming too long due to the folder 
being longer. A simple fix for this should be to set the "parallel" attribute 
on chmod to false.
