Not true. HOD has python unit tests and is the reason our builds
have dependencies on python.
But Allen's point is that I don't recall ever seeing HOD test failures
causing the build to fail.
b) The edu community uses this quite extensively, evidenced by the
topic coming up on the mailing lists at least once every two months
or so and has for years. Can't say that about the other contrib
modules other than the schedulers and streaming.
Then they are using old version of Hadoop. AFAICT HOD does not work
with 0.20 or beyond.
Out of curiosity, what goes wrong? Clearly nothing major has changed
in starting up a mapreduce cluster in a very long time.
c) The community that does use it has even submitted a patch that
we've ignored.
Which means the committers of this project gave up on it long ago.
There are also some patches on core Hadoop that have been sitting for
a long time, so I don't think that is a valid inference.
I would love to hear some of the people who are using HOD speak up and
give us their feedback.
