Aaron T. Myers commented on HADOOP-8924:
----------------------------------------

Hey guys, does it really make sense to trade a dependency on sh for a dependency on python? Maybe it does, but at least on Unix systems I feel like sh is more likely to be available than python. (Honest question here - not trying to be a pain.)

At the very least, if we stick with this being in python, we should update BUILDING.txt to say that we now have a dependency on python (and perhaps some specific version of python?) in order to build Hadoop.

> Currently, the build process relies on saveVersion.sh to generate package-info.java with a version annotation.  The sh binary may not be available on all developers' machines (e.g. Windows without Cygwin). This issue tracks removal of that dependency in Hadoop Common.
