PIG UDF ERROR

maturcot — Thu, 12 May 2016 00:37:30 GMT

I managed to create a UDF, successfully compiled it and packaged it in a customudf.jar file that is located here on a HDP 2.4 sandbox: /user/maria_dev/customudf.jar. I start my PIG script with

...and I created a entry the web interface for UDF as follows:

UDFs

Name: customudf

Path: /user/maria_dev/customudf.jar

Owner : maria_dev

Yet, when I run my PIG script the line customudf.xformation(f1) generates a non descript error:

ERROR org.apache.pig.tools.grunt.Grunt - ERROR 101: file 'customudf.jar' does not exist.

What am I missing?

2) Change the REGISTER line to the following:

this works for me just by adding hdfs:/// in the path without changing file to .jar

Thanks
