User interfaces

This section briefly describe user interfaces and class components of the map/reduce API.

The version of the map/reduce API was designed to be similar to standard Hadoop map/reduce. However, to take advantage of the AMPP environment, there were changes made in the API that prevent full compatibility and require some map/reduce jobs to be rewritten.

There are two sets of classes that can be used to implement a map/reduce job. These classes are located in two separate packages: org.netezza.inza.mr.mapred and org.netezza.inza.mr.mapreduce. This document describes classes from the org.netezza.inza.mr.mapreduce package.
