Hadoop::Streaming 0.102490 pushed to CPAN

I've pushed a new release of Hadoop::Streaming to CPAN. It should be available in a couple of hours, depending on how long it takes your CPAN mirror to do the mirror update dance.

The release includes expanded documentation in the base Hadoop::Streaming placeholder file. Also included is a Hadoop::Streaming::Combiner role, for creating combiners. Combiners are like reducers that run post-map, per-merge. Once can reuse the reducer as combiner, if the reducer produces the same key/value format on output as input.

After writing my new documentation, test and code, I tested it with dzil test. After passing tests, it's a simple 1 step push to CPAN and github via dzil release. AWESOME! Dist::Zilla makes maintaining CPAN modules brilliantly easy.

Happy Labor Day!
