Help in Class IndexRecord

The class IndexRecord has these 2 fields:

long rawLength;
long partLength;


1 - I'm guessing that partLength contains the size of a partition in a
MapOutput.  For example, each partition in the MapOutput contains a
IndexRecord class, and the partLength contains the length of the partition.
 And what contains rawLength?

2 - The map output contains a header. If a map output contains 2
partitions, this file contains 1 or 2 headers?
