This concerns the latest version of Mahout checked out from the SVN repo (I believe 0.4)
When launching TestClassifier using:
$MAHOUT_HOME/bin/mahout testclassifier -m model -d test-input -type cbayes -ng 1 -source hbase
The output says that the classifier type is Bayes (not Complementary) and the data source is HDFS.
After a quick investigation in TestClassifer.java source, there are mistakes on lines: 142, 147, 148
with classifierType instead of typeOpt, and dataSource instead of dataSourceOpt
