-----------------------------------
Summary: mapreduce split causes ClassNotFound exception
Key: MAHOUT-1061
URL: https://issues.apache.org/jira/browse/MAHOUT-1061
Project: Mahout
Issue Type: Bug
Components: Integration
Affects Versions: 0.7
Reporter: David Engel
Running the split program in mapreduce mode, e.g. "mahout split -xm mapreduce
..." results in a ClassNotFound exception because the job jar is not set. The
following patch fixes the problem for me.
