Description

Say you have a HiveMetaStore field:

llama    array<string>

HCatalog converts to the first format below, while other systems may convert differently (such as elephant-bird which is listed second). This causes issues for all existing pig queries.

llama: {innertuple: (innerfield: chararray)}  <-- HCAT
llama: {t: (llama_tuple: chararray)}  <-- ELEPHANT-BIRD

The conversion names should be configurable.
