when I use mahout 0.4 to execute on a hadoop cluster:
*
./mahout org.apache.mahout.clustering.syntheticcontrol.canopy.Job --input
/mahout/input --output /mahout/output13 -t1 80.0 -t2 50.0*
it works very well..
but when I use mahout 0.5 to execute *the same command(if omitting the
output dire
I think you have changed your classpath to use 0.5, and in your new
classpath, you are not including all the jars. You probably need core, math,
and collections at minimum.

hi, Sean, for 0.4 and 0.5, I use the same settings ,in fact no settings, I
just download them and unpack them, and then use them to do some test...
anyone meet this kind of problem ? thank you .

OK, well the underlying problem remains that it cannot find the mahout-math
jar file in the classpath. It's not a problem with 0.5 per se, but something
to do with finding the jars.

but, what should I do now , it is a very strange problem, 0.4 works well,
but 0.5 does not [?]

Like I said, it's a classpath issue. The script likely changed between 0.4
and 0.5, so you need to look at what its classpath is, where it's looking
for jars and understand why it is not finding what you need in your
environment.
It works out of the box, so I think it is an issue specific to you. U
Hi,
I had the same issue and broke my head over it , I guess this might help .
mahout in calling this hadoop code form inside , I am using it instead to
run my canopy and kmeans clustering algorithms . (this worked for the
cloudera vm and also on my hadoop dev cluster , )
use this instead, /home/
i have the same problem. my solution is try to run mahout-*-job.jar. specify
the class.
