Prasad Chakka commented on HIVE-337:
------------------------------------
just to clarify what i meant,
a null array, an empty array and an array with one empty string or null are all
same. So users can't rely on being able to differentiate between the 4 cases.
All of them are represented by an empty string in the serialized string of the
array. such an array should be deserialzied to either null or empty array. i
prefer a null array since it is easier to test for in conditions.
> LazySimpleSerDe should support array and map types
