Hello Big Data SIG!
A few of us in the Fedora community have been working to package Apache
Hadoop for Fedora. The feature page is,
https://fedoraproject.org/wiki/Features/Hadoop
You'll find what we plan to package, our progress working through all
the dependencies, a process for how we're attacking dependencies and a
pre-Fedora repo of the packages in progress.
It's a big effort, but will form a foundation for packaging more Hadoop
ecosystem packages for Fedora.
We're at a point where we need a better place to engage the community
and the Big Data SIG is a natural choice. I hope you will welcome us to
the list and IRC, and maybe lend a hand!
