I've found that there are two different implementations of seemingly the same class:
MultiFileLineRecordReader (implemented as an inner class in some versions of MultiFileWordCount) and CombineFileRecordReader In order to implement RecordReaders for the MultiFileWordCount class. Is there any major difference between these classes, and why the redundancy ? I'm thinking maybe it was retro added at some point, based on some git detective work which I tried... But I figured it might just be easier to ask here :) -- Jay Vyas http://jayunit100.blogspot.com
