Re: Hadoop Serialization mechanisms

- You can override the RPC serialisation module and engine with a
custom class if you wish to, but it would not be trivial task.
- You can easily use custom data serialisation modules for I/O.
While MR's built-in examples in Apache Hadoop continue to use
Writables, the RPCs have moved to using Protocol buffers for
themselves in 2.x onwards.
Yes "partially", see above.
Yes, you should see a gain in using a more efficient data
serialisation format for data files.
