I had entered a JIRA here:
https://issues.apache.org/jira/browse/HADOOP-9206 . The instructions
for single-node setup on 1.1.x are radically different from the
instructions for 0.23 and 2.0.2; furthermore, the JARs and folder
structure of what you get from the 1.1.x download and what you get with
either 0.23.x or 2.0.x-alpha is also considerably different. The deltas
here, along with Bobby Evans' explanation of the version histories I
linked to above, gave me the impression that 1.x has one team working on
it while the other branches have another. If that was the case (as
you're not clarifying, it's not) I was then wondering when all
committers would be more or less on the same page again.
Thanks for the clarification.
