Ryan Blue updated HIVE-8909:
----------------------------
Attachment: HIVE-8909.3.patch
Updated patch with q tests for all of the cases in TestArrayCompatibility. I
also added a q test that copies nested_complex.q that produces the same results.

> Parquet's Avro and Thrift object models don't produce the same parquet type
> representation for lists and maps that Hive does. In the Parquet community,
> we've defined what should be written and backward-compatibility rules for
> existing data written by parquet-avro and parquet-thrift in PARQUET-113. We
> need to implement those rules in the Hive Converter classes.
