I think you'll want to look at the Hadoop Streaming or Hadoop Pipes API.
Further down the line, I think somebody will want to implement a Haskell
library to deal with the Avro serialization protocol when it becomes
possible to write non-JVM mappers and reducers directly. This JIRA issue
covers the RPC part of the Avro-Hadoop integration work:
https://issues.apache.org/jira/browse/HADOOP-6659
Looks like folks have already implemented support for Thrift and
Protocol Buffers, so implementing a library for Avro would likely be
pretty similar.
