[jira] [Created] (MAHOUT-894) NB testclassifier runs in sequential
mode by default
NB testclassifier runs in sequential mode by default
----------------------------------------------------
Key: MAHOUT-894
URL: https://issues.apache.org/jira/browse/MAHOUT-894
Project: Mahout
Issue Type: Bug
Components: Classification
Affects Versions: 0.6
Reporter: tom pierce
NB classifiers can only be trained in MR mode, but evaluation happens in sequential mode by default. I think this violates the principle of least surprise - anyone trying this out is likely to expect the opposite.
I'm attaching a patch to flip the default.
