Sean Owen updated MAHOUT-510:
-----------------------------
Attachment: MAHOUT-510_part_2.patch
As an encore, I did find more use of JSON and here's another change as a
result. It came up while looking at the vector-related Driver classes, which
have an option to dump to SequenceFile or JSON. I removed the JSON option,
though it could be left in as a "dump as some text" option though I don't know
if that's useful or just more confusing. I renamed the "JWriter*" classes as
they no longer involve "J"SON.

> At the moment this is tracking a broader concern: to standardize as much as
> possible how we approach serialization. The long-term goal is notionally to
> use the following "encodings" as the input/output of Mahout stuff, and by
> extension, probably internally too.
> - Text
> - Vector Writable
> - (maybe Avro)
> not
> - Serializable
> - GSON / JSON
