Subject [jira] Updated: (MAPREDUCE-1480) CombineFileRecordReader does not properly initialize child RecordReader
Date Thu, 11 Mar 2010 21:56:27 GMT

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

Dhruba, I agree that your proposed {{getProgress()}} method should work; I've folded it in
here as well.

> CombineFileRecordReader instantiates child RecordReader instances but never calls their
initialize() method to give them the proper TaskAttemptContext.
