---------------------------------------

{~szita]:  LGTM
Add more comment like "in spark mode, we need to load the script by 
Thread.currentThread().getContextClassLoader ..."  before following kind of code

{code}
 if (udfFileStream == null) {
                udfFileStream = 
Thread.currentThread().getContextClassLoader().getResourceAsStream(filePath+getUserFileExtension());
            }
{code}
