Subject XXXWritable
Date Mon, 04 Jul 2011 01:32:43 GMT


I read in Definitive guide that, LongWritable and xxWritables are more
optimized versions for network serialization of normal Java Long etc..

If that is so, would be not be easy for developers to use normal Java long
and string, so hadoop framework can internally convert the developer written
code to use the longwritable etc or through some intermediate code
conversions. This approach can greatly reduce the no of api and helps in
faster learning.

Not sure, why developer had to write and use XXXWritable etc in the context
of optimized for network serialization
