Alan Gates commented on PIG-2332:
---------------------------------
One comment. I didn't see any tests that check that it can properly read null
data. It looked like it was writing null data in one of the unit tests. But I
think we should check that it can read it too. Changing one of the nightly
tests to use studenttabnull10k would do it.
Other than that, look good. +1.

> A JsonLoader/JsonStorage implementation for Pig. This is based on Alan's
> implementation in the book
> (http://ofps.oreilly.com/titles/9781449302641/load_and_store_funcs.html). I
> made some minor changes:
> 1. Drop the jackson feature requires 1.01+. Since Hadoop 203+ bundles jackson
> 1.01, newer feature fails when running on Hadoop 203+.
> 2. Using Json format for schema. This borrows Dmitry's schema implememtation
> in PigStorage.
> 3. Some bug fixes.
