Starting a MapReduce-Job with MongoDB-hadoop connector from Java

[Jonas F.]

Hi, what I want to do is to start a MapReduce-Job in Hadoop that gets its input from MongoDB and writes its output to MongoDB.
This job should be started from a java application.

Cassandra has a nice documentation for this case: http://www.datastax.com/docs/0.7/map_reduce/hadoop_mr

For MongoDB I only find a very short doc on the hadoop connector: https://github.com/mongodb/mongo-hadoop

Are there any sources I didn't find?

Thanks for your help!
