I tried both in my home driectory and it worked fine and also it worked fine when i had my parm file on s3. But its not working when i try to do it from hdfs.

@Pradeep Allu did you try Suresh's idea? Can you accept the answer or add more detail

@Pradeep Allu

If your parameter parameter file is in hdfs then make sure your pig script should also be in hdfs not in local file system.

Try placing your pig script also in HDFS .

@Pradeep Allu try to pass just the directory path rather than full path including hdfs. Maybe put the path in quotes also?
