Package org.apache.avro.mapred.tether Description

Run Hadoop MapReduce jobs over Avro data, with map and reduce functions run in a sub-process. This permits MapReduce programs over Avro data in languages besides Java.

Each language will provide a framework to permit easy implementation of MapReduce programs in that language. Currently only a Java framework has been implemented, for test purposes, so this feature is not yet useful.

This is still an experimental API, subject to change.
