Chris Nauroth commented on HADOOP-8924:
---------------------------------------
On branch-trunk-win, when we converted to Python, I consolidated to a single
copy of saveVersion.py in /dev-support, which is used by both sub-modules. I
needed to introduce some additional arguments to the script so that it could be
parameterized differently for hadoop-common vs. hadoop-yarn-common. It didn't
add much complexity, and it eliminated the need to maintain 2 different copies
of the same code. We could take the same approach to parameterize the
equivalent Java code (or whatever else).
> Hadoop Common creating package-info.java must not depend on sh, at least for
> Windows

> 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.
