Mahout compatibility with Hadoop

2013-06-17 Thread Razon, Oren
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

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

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

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:

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.) On Mon, Jun 17, 2013 at 2:58 PM, Sebastian Schelter ssc.o...@googlemail.com wrote: On 17.06.2013 15:56,

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.

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. On Mon, Jun 17, 2013 at 3:23 PM, cont...@dhuebner.com wrote: Well, I just setup up CDH4 with Mahout for testing a few days ago. It still required some fixing of

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 oren.ra...@intel.com wrote: Thanks Sebastian Sean. I know Cloudera and other distributions until lately supported only Mahout 0.5 which made me

(Kinda doing something very close. ) Koren-Volynsky paper on implicit feedback can be generalized to decompose all input into preference (0 or 1) and confidence matrices (which is essentually an observation weight matrix). If you did not get any observations, you encode it as (p=0,c=1) but if
