Subject Retrieve the segments as bytes at RT
Date Tue, 01 Feb 2011 22:11:18 GMT

1 - In the example that I'm executing, during the phase of copying the
map output from Map task to Reduce task, the RT saved the map output
into disk, because it's to big.

I've go the file path to the saved map output, and now I would like to
retrieve the following information:

- checksum
- the size of the checksum
- the body part of the file in bytes. What I mean as body, is all the
segments of the map output in bytes.

How can I do that?
