Description

Hi folks.

Looks like rc08 is using the old mahout, not the new one. I.e. its build for hadoop 0-1x.. not for hadoop 2x .Poking aroudn on RC testing today, I found this.

1) yum list output shows:

mahout.noarch                                       0.9.6-1.el6                                       @Bigtop
 

The 0.9.6--1 seems suspicious.

2) And I ran the mahout tests on a clean RC08 repo, and I got some errors indicating that it was built for hadoop 1 class found but interface expected... indicating that it is an older mahout api which is running the job.

(a side note : i also saw that pom.xml has references to hadoop 0.23, but looking at other mahout packages from vendors, its clear that some how that remains in the mahout pom for some reason or another , so thats not an issue. the main evidence pointing to bad mahout version is that #2 error i sited above )
