Dear Wiki user, You have subscribed to a wiki page or wiki category on "Pig Wiki" for change notification.
The "LoadStoreMigrationGuide" page has been changed by PradeepKamath. http://wiki.apache.org/pig/LoadStoreMigrationGuide?action=diff&rev1=19&rev2=20 -------------------------------------------------- - 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 implemented a custom OutputFormat. + 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.

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 on org.apache.hadoop.mapreduce package instead of the old org.apache.hadoop.mapred package.
