-----------------------------------------

Chris is asking for this to hold up on HADOOP-4010 to go in first.

> 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).
