@Yukti Agrawal , the answer is no. But if you have HUE installed in your cluster, you should see some scripts. Check under this folder /usr/lib/hue/apps/oozie/examples.

Or do simply run locate command to search it.

I would recommend to create a simple script if you just want to test pig. Store a sample csv in HDFS and load that file in Pig:

A = LOAD '/the/path/in/HDFS/sample.csv' USING PigStorage(',') AS (driverId:int, truckId:int, driverName:chararray);

some_columns = FOREACH A GENERATE driverId,driverName;

STORE some_columns into 'output/some_columns' using PigStorage(',');

Unfortunately we dont have HUE in our cluster. Also locate command is not working in my client's env. I will try this script, hoping it will help.
