Re: Mahout compatibility with Hadoop
Hi Oren, you should be able to run Mahout with the latest 0.20.2x and 1.0.x and 1.1.x Hadoop releases. I personally use the current trunk (which will be released as 0.8 soon) with Hadoop 1.0.4 and have not experienced any problems. I would strongly encourage you to also use the trunk or wait a little for 0.8, as we fixed lots of bugs and increased performance in a lot of places.

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.

RE: Mahout compatibility with Hadoop
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?) -Original Message- From: Sean Owen [mailto:sro...@gmail.com] Sent: Monday, June 17, 2013 4:53 PM To: Mahout User List Subject: Re: Mahout compatibility with Hadoop Is it compatible with any Hadoop release? of course, would it make sense if not?

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. -sebastian > > > -Original Message- > From: Sean Owen [mailto:sro...@gmail.com] > Sent: Monday, June 17, 2013 4:53 PM > To: Mahout User List > 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.

Re: Mahout compatibility with Hadoop
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.)

Re: Mahout compatibility with Hadoop
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. On 2013-06-17 16:03, Sean Owen wrote: CDH3 has 0.5 + patches, CDH4 has 0.7 + patches.

Re: Mahout compatibility with Hadoop
Yes you have to refer to the 'mrv1' artifacts if I recall correctly, if you use CDH4. You are talking about CDH3, which is different.

Re: Mahout compatibility with Hadoop
Not sure which distributions you mean when you say "other distributions". MapR includes Mahout 0.7. On Mon, Jun 17, 2013 at 3:56 PM, Razon, Oren wrote: > Thanks Sebastian & Sean.
