Jonathan Packer commented on PIG-1914:
--------------------------------------
A note about handling arrays: the proposed JsonLoader will wrap the values of a
flat JSON array, ex. "arr": [1, 2, 3, 4], in single-element tuples by default.
However, if a tuple schema, for example coords: (lat: double, long: double), is
specified for a field which is a flat JSON array, the JsonLoader will cast the
array to a tuple. Nested arrays are loaded properly if a valid schema is
specified.
