> {{HiveFunctionWrapper#getUDFClass}} currently uses {{Class.forName(className)}} to load Hive UDF classes, while {{HiveFunctionWrapper#createFunction}} uses {{Thread.currentThread().getContextClassLoader()}}.
> {{HiveFunctionWrapper#getUDFClass}} should also use {{Thread.currentThread().getContextClassLoader()}} as it is loading user classes.
