  This page describes how to migrate from the old !LoadFunc and !StoreFunc 
interface (Pig 0.1.0 through Pig 0.6.0) to the new interfaces proposed in 
http://wiki.apache.org/pig/LoadStoreRedesignProposal and planned to be released 
in Pig 0.7.0. Besides the example in this page, users can also look at 
!LoadFunc and !StoreFunc implementation in the piggybank codebase 
(contrib/piggybank/java/src/main/java/org/apache/pig/piggybank/storage) for 
examples of migration. For example, !MultiStorage implements a custom 
!OutputFormat.
  
  '''A general note applicable to both !LoadFunc and !StoreFunc implementations 
is that the implementation should use the new Hadoop 20 API based classes 
(!InputFormat/OutputFormat and related classes) under the 
org.apache.hadoop.mapreduce package instead of the old org.apache.hadoop.mapred 
package.'''
