Samar Lotia created MAHOUT-1141:
-----------------------------------
Summary: Driver for cvb0_local does not warn about missing
maxIterations command line parameter
Key: MAHOUT-1141
URL: https://issues.apache.org/jira/browse/MAHOUT-1141
Project: Mahout
Issue Type: Bug
Components: Clustering
Affects Versions: 0.7, 0.8
Environment: MacOS 10.8, Java 7
Reporter: Samar Lotia
Priority: Minor
The driver for cvb0_local does not seem to verify that the caller has specified
the required maxIterations command line parameter. This results in an exception
much further down which pretty much requires looking at the source to discover
the source of the error.
Exception in thread "main" java.lang.ClassCastException: java.lang.Integer
cannot be cast to java.lang.String
