> Key: MAHOUT-427
> URL: https://issues.apache.org/jira/browse/MAHOUT-427
> Project: Mahout
> Issue Type: Bug
> Affects Versions: 0.4
> Environment: Hadoop installation on EC2 as described here -
> https://cwiki.apache.org/MAHOUT/mahoutec2.html
> Reporter: Peter Goldstein
>
> Once I resolved issue MAHOUT-426 , I was still not able to run the
> ./examples/bin/build-reuters.sh script without errors These were
> ClassNotFoundExceptions, indicating a problem with the classpath.
> The issue appears to be related to the "-core" argument, which controls the
> classpath. Placing '-core' as the first argument to the individual
> $MAHOUT_HOME/bin/mahout calls in the script solved the issue, but I'm not
> sure it was the correct solution. It's unclear to me what the '-core'
> argument is supposed to signify.
> Can someone shed some light on this, and tell me whether this is the correct
> solution to the problem? And if not, what is the correct solution to this
> classpath issue.
