This is more of a Hadoop question. The input hides behind the InputFormat implementation. If you have an InputFormat that can read and produce the same key-value pairs that you'd get from a SequenceFileInputFormat / TextInputFormat and HDFS, yes the rest just works automatically. You have to modify the code though.
