> Avro should provide Hadoop Mapper and Reducer implementations that connect to a subprocess in another programming language, transmitting raw binary values to and from that process.  This should be modeled after Hadoop Pipes.  It would allow one to easily write efficient mapreduce programs in non-Java languages that process Avro-format data.
