Siva, the first thing I do is test the Hive UDF in Hive. once that works I begin moving it into Drill. I'm assuming you have your empty drill-module.conf file, classes, and source files in your jars and have put them in the drill class path say <your-drill>/jars/3rdparty.
When you restart your drill pits you can do a tail on the <your-drill>/logs/drillbit.log file and look to see if drill had any complaints during the UDF loading on startup.
