> ----> 1 thresholded = df.filter(df['udt_time'] > threshold)
> AnalysisException: u"cannot resolve '(`udt_time` > TIMESTAMP('2015-10-20
> 01:00:00.0'))' due to data typ mismatch: '(`udt_time` > TIMESTAMP('2015-10-20
> 01:00:00.0'))' requires (boolean or tinyint or smallint or int or bigint or
> float or double or decimal or timestamp or date or string or binary) type,
> not pythonuserdefined"
> {code}
