Samar Lotia updated MAHOUT-1141:
--------------------------------
Description:
The driver for cvb0_local does not seem to verify whether 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
