Unable to add file paths when registering a UDF
Hello,
I am trying to use a User Defined Function and I am unable to get Pig
to recognize my compiled jar file when I have a path to the file. The
file works when I put the jar file into the working directory for Pig,
but I am a teaching assistant for a big-data course and we need
students to put their work in their respective directories.
Below is my pig script for my application:
REGISTER MovingAverage.jar;
--REGISTER /class/s14419x/lab7/MovingAverage.jar;
The first line works, but the second gives me:
ERROR org.apache.pig.tools.grunt.Grunt - ERROR 101: file
'/class/s14419x/lab7/MovingAverage.jar' does not exist.
I am teaching UDFs for a lab tomorrow so I would really appreciate any
help or insight you could offer.
Also, big fan of Pig. Keep it up!
Tony

Or is it a network mount?

According to the docs, It should work.
http://pig.apache.org/docs/r0.12.0/basic.html#register
Stupid question, but is the path correct? Is it on HDFS or local disk?
