Hi, Hadoop uses the compressed length and the raw length.
1 - In my example, the RT is fetching a map output that shows that it has the raw length of 14 bytes and the partLength of 10 bytes. The map output doesn't use any compression. When I'm dealing with uncompressed data, the raw length should be 14 and the partlength 0? I'm saying this because, the data that is being transferred to the RT is uncompressed. 2 - The raw length of the map output is the size of the block (10 bytes) + header? 3 - part length means partition length? Thanks, -- Pedro
