Description

Example. This is how you use the AvroStorage UDF in Piggybank:

register /me/pig/contrib/piggybank/java/piggybank.jar
register /me/pig/build/ivy/lib/Pig/avro-1.5.3.jar
register /me/pig/build/ivy/lib/Pig/json-simple-1.1.jar
define AvroStorage org.apache.pig.piggybank.storage.avro.AvroStorage();
emails = load '/enron/emails.avro' using AvroStorage();

That is 5 lines. This should be 2 lines:

import 'avro.macro'
emails = load '/enron/emails.avro' using AvroStorage();
