Re: [VOTE] introduce Python as build-time and run-time dependency for Hadoop and throughout Hadoop stack

-1, +1, -1

Run- & build-time scripting should be limited to operations that are
impossible in Java.  These should not be complex nor should we
encourage more complexity in them.  A parallel set of simple .bat
files for such operations seems preferable to adding a Python
dependency.
