> Make the format of the Job History be JSON instead of Avro binary

> I forgot that one of the features that would be nice is to off load the job
> history display from the JobTracker. That will be a lot easier, if the job
> history is stored in JSON. Therefore, I think we should change the storage
> now to prevent incompatibilities later.
