Aaron Kimball updated MAPREDUCE-1480:
-------------------------------------
Attachment: MAPREDUCE-1480.3.patch
New patch addressing the above. Added a {{testReinit()}} testcase that checks
multiple files in the same CombineFileSplit and ensures that {{initialize()}}
got called correctly the second time.
Dhruba, I agree that your proposed {{getProgress()}} method should work; I've
folded it in here as well.
> CombineFileRecordReader does not properly initialize child RecordReader
