[jira] [Created] (HIVE-8909) Hive doesn't correctly read Parquet nested types

Ryan Blue created HIVE-8909:
-------------------------------

             Summary: Hive doesn't correctly read Parquet nested types
                 Key: HIVE-8909
                 URL: https://issues.apache.org/jira/browse/HIVE-8909
             Project: Hive
          Issue Type: Bug
            Reporter: Ryan Blue
            Assignee: Ryan Blue


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.
