Affects Versions: 1.6.0
Environment: Red Hat 6.6, Spark 1.6.0, Python 2.7.10 (anaconda)

An UDF cannot return a numpy type, it has to be one of the Python basic types.
The error when a numpy type is returned is
TypeError: ufunc 'nan' not supported for the input types, and the inputs could
not be safely coerced to any supported types according to the casting rule
''safe''
