Amareshwari Sriramadasu updated HADOOP-5710:
--------------------------------------------

    Attachment: patch-5710-2.txt

Patch incorporating review comments. Earlier patch had findbugs warning saying Unchecked/unconfirmed cast fromTaskAttemptContext to MapContext . Added the warning to exclude list, since the warning is unavoidable.

> MapTask, with current new mapreduce api, does not maintain MAP_INPUT_BYTES counter. Since RecordReader doesnot have getPos() api, it is not possible for the map task to maintain. Individual record readers (LineRecordReader, SequenceFileRecordReader) could be modified to maintain the same.
