Python has fairly inconsistent support across all major OS vendors. It is
hard to get it right unless the scripts are all designed to make use of

Hi Doug,
I didn't read your email until this morning, but I spent time overnight

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.

Matt,
Let me repost my previous questions and a few more. I'd appreciate your
answers, as it will help me understand the full impact this would have in
Hadoop and related projects.

scripts provided by Hadoop (or dynamically
Python as runtime requirement. Are you planing to migrate all

scripts) to Python?
I don't intend to mandate use of Python. Rather, I want there to be a
cross-platform option available. Things that are best done in

Supporting Comments:
Build-time scripts: Using a platform independent language such as python (or
maven in certain cases) will greatly help in reducing build breaks and improve
on build script maintainability.
Run-time scripts: Most run-time scripts are end-user
Hello again. Crossed in the mail.

not possible today?
The point isn't to open brave new worlds. The point is to avoid the
nightmare of having to maintain multiple parallel scripts doing the SAME
THING in multiple scripting

Agree with Matt on the code maintainability.
I think on one side we have Shell which is a script language and OS dependent,
e.g. as in bash vs powershell;
on the other side we have Java which is not a script language and OS
independent.
I would accept any script language that can fix

We have had promising results for 1 and 2 when porting to Windows. 3 would
allow us to remove platform dependencies from test code. Agree that there
might be some nuanced operations that require OS specific environments but
this would lead to keeping them at a minimum.

In the PROPOSAL thread you indicated this was for Hadoop1 because it is ANT
based. And the main reason was to remove saveVersion.sh.
Your #3 was not discussed in the proposal, was it?
it was part of original proposal but not discussed much because language
