----------------------------------
Summary: HighDFWordsPrunerTest is failing silently
Key: MAHOUT-1336
URL: https://issues.apache.org/jira/browse/MAHOUT-1336
Project: Mahout
Issue Type: Bug
Affects Versions: 0.8
Reporter: Mike Percy
Fix For: 0.9
Apparently ToolRunner does not allow the --mapred option. The validation is not
very foolproof, so there is a resulting silent failure in HighDFWordsPrunerTest.
Error message:
{noformat}
org.apache.commons.cli2.OptionException: Unexpected --mapred while processing
