Hadoop 0.19/0.20
I'd like to upgrade from 0.17 to 0.19 to get my hands on hdfs append.
Are there any objections to that? I'm not sure wether or not 0.19
contains append in SequenceFile.Writer, but if not then I'd want to
switch to 0.20 (trunk). It's MAHOUT-19 that require this feature.
I could also wait another month or two, no problem.

Append was not quite as supported as I hoped for it to be. Just added
HADOOP-3977 and it makes very little sense (for me) to upgrade Mahout
until it has been reviewed, cleaned up and and committed.

I'm running 1.6 and Hadoop 0.19-dev in my local MAHOUT-19 setup. It
seems to work just fine. I'll run it a bit more before I commit
anything.

Hmmm, 1.6. Didn't realize that. What do people think of it? I guess
now that Mac has 1.6 I'm fine w/ it. Only scary part for me is I've
seen a number of people complain about 1.6 in Lucene/Solr in terms of
really odd bugs, especially on Linux, but that may not be a problem
for us.
On the flip side, if Hadoop is going to 1.6, then we really don't have
any choice, since it's not like we are going to stick w/ Hadoop 0.17
forever.
So, +1 assuming the tests pass, etc.

I'm OK with it myself. Go for it and I'll fix up any incompatibilities
in my part of the code.

0.17.1 is the lastest offical release. 0.19 is trunk and it depends on
JDK 1.6.

Is it out yet? At any rate, in this stage of the game, I say upgrade
early, upgrade often.
