I can confirm what Sebastian said, I'm fairly new on this and I did find
myself so desperate at some point that I almost gave up on Mahout dut to
lack of documentation, but my feeling is that it doesn't only concerns the
website : the API is too few documented as well. At this point there are no

issue for that work before you start.

Hi,
I tried to fix all the problem I had to configure eclipse in order to

First I had to make a change in mahout core in the class GroupTree.java,
line 171 :

Then I tried compiling with eclipse (I

Pca and ssvd propagates exact row keys given in the input. If you give it

Hi everyone,
Is there a simple way to install Mahout 0.9 on a cluster running Cloudera's
CDH 4.5 ?
When I try what they advise on their doc (yum install mahout on my CentOS 6
node), it wants to install mahout version 0.7+22-1.cdh4.5.0.p0.14.el6.
Thanks in advance !
