Owen O'Malley updated HADOOP-4293:
----------------------------------

    Attachment: 4293-2.patch

This patch:
  1. Changes the name of Configuration.write to writeXml.
  2. Makes Configuration Writable.
  3. Makes the new binary format a vint length, followed by 2*N Texts.
  4. Removes WritableJobConf from the mapred package.

I'll create a new jira proposing that we use the binary file format instead of 
the job.xml for job submission.

> The new class WritableJobConf doesn't add value over just making JobConf 
> Writable, and I propose that we remove it before it is released.
