I got hadoop 1.0.2 working with mongo-hadoop on ubuntu 12.04LTS
successfully.

Question on the wordcount program.

https://github.com/mongodb/mongo-hadoop/blob/master/examples/wordcoun...

        job.setCombinerClass( IntSumReducer.class );
        job.setReducerClass( IntSumReducer.class );

        job.setOutputKeyClass( Text.class );
        job.setOutputValueClass( IntWritable.class );

        job.setInputFormatClass( MongoInputFormat.class );
        job.setOutputFormatClass( MongoOutputFormat.class );

1. The input class is not defined I think that the input class in java
can be inferred by the query object. (DBObject)
2. Is it customary set the OutputValueClass ( MyCustomClass.class) or
is it more idiomatic to use hadoop's data types?
