Subject [jira] Created: (MAPREDUCE-773) LineRecordReader can report non-zero progress while it is processing a compressed stream

LineRecordReader can report non-zero progress while it is processing a compressed stream
----------------------------------------------------------------------------------------

                 Key: MAPREDUCE-773
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-773
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: task
            Reporter: Devaraj Das
            Assignee: Devaraj Das
             Fix For: 0.21.0


Currently, the LineRecordReader returns 0.0 from getProgress() for most inputs (since the
"end" of the filesplit is set to Long.MAX_VALUE for compressed inputs). This can be improved
to return a non-zero progress even for compressed streams (though it may not be very reflective
of the actual progress).
