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? -- Thanks, PSC
