I think we can release just the merged artifact. It contains the
source code for the three subprojects, and you can build separate
binaries from it, if needed.

I think this is because HADOOP_HOME was not set. We can improve this
to default HADOOP_HOME if not set; I'll create a JIRA.

I've created HADOOP-6917 and HDFS-1349 to tackle these.

With three binding PMC +1 votes, the vote passes. I'll start work to
push out the release.
