Well, I just setup up CDH4 with Mahout for testing a few days ago. It
still required some fixing of the pom file to build mahout (provided
from cloudera) and some of the tests failed (the only one I remember had
something to do with ALS).
Nevertheless, I just tried it and didn't really test it. CDH4 still
comes in two flavors, which should be taken into account. One keeps
using the "old" 0.2x version of Hadoop and the other one uses the alpha
2.xx versions.

CDH3 has 0.5 + patches, CDH4 has 0.7 + patches.
I suppose the good news there is that recent versions must work OK
with Hadoop 2.x, since CDH4 = Hadoop 2. (I didn't suspect otherwise.)

Thanks Sebastian & Sean. I know Cloudera and other distributions
until lately supported only Mahout 0.5 which made me suspect.
I will go and use Mahout 0.8 (assuming it should be officially
released any day now, right?)
I guess the Cloudera folks should do an upgrade, 0.5 is really an
ancient release.
We have two or three issues left for 0.8, then we'll have a code
freeze
and do testing before we release 0.8.

Subject: Re: Mahout compatibility with Hadoop
Is it compatible with any Hadoop release? of course, would it make
sense if not?
I'm not sure where you get this idea. 0.5 was, I think, compiled vs
0.20.x. The last release was vs 1.0.3 or so. The current release is
vs 1.1.x. In all cases these are the latest stable Apache releases,
so not sure what you are referring to.

Hi,
From what I saw so far it seem that only Mahout 0.5 (the Hadoop
part) is compatible with Hadoop latest releases, and that later
Mahout releases are not officially supported.
I wonder if anyone know if Mahout 0.7\0.6 is compatible with any
Hadoop release?
Thanks,
Oren
