I need to use Mahout 0.9 for a project. It is said that Mahout 0.9 works well with hadoop 1.x, and there are some problems with hadoop 2.x compatibility. Therfore I need to have Mahout 0.9 and hadoop 1.x. By default HDP 1.3.3 has Mahout 0.7 according to the sources. Can I upgrade Mahout to 0.9 after I install HDP 1.3.3?
If Mahout 0.9 works well with hadoop 2.x, then there is no problem. But can someone assure that to me.
In the last release of HortonWorks DataPlatform (2.1) of April 2014 Mahout 0.9 is supported. I used mahout 0.9 with Hadoop 2.3 and I didn't have any problem so i guess there is no reason to not use it.
