Hadoop for the lone analyst, part 2: patching and releasing to yourself

We left off, in part one of this series, at the point where we had Hadoop running with the Cloudera distribution, version 0.20.1+152. That’s Apache Hadoop release 0.20.1, plus 152 patches that Cloudera’s copious experience tells them they need for work in the real world.
