Subject Re: Mahout compatibility with Hadoop
Date Mon, 17 Jun 2013 14:23:30 GMT
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.
