Description

Long-running map tasks don't update properly their progress - the propgress percentage stays at 0% only to jump suddenly at the end of the task to 100%. The reason, discovered by Espen Amble Kolstad, is that there's a missing cast to float in SequenceFileRecordReader and in LineRecordReader.
