CDPD-40730: Parquet change can cause incompatibility

Parquet files written by the parquet-mr library in CDP 7.2.16, where the schema contains a timestamp with no UTC conversion will not be compatible with older versions of Parquet readers. The effect is that the older versions will still consider these timestamps as they would require UTC conversions and will thus end up with a wrong result. You can encounter this problem only when you write Parquet-based tables using Hive, and tables have the non-default configuration hive.parquet.write.int64.timestamp=true.

CDPD-15518: ACID tables you write using the Hive Warehouse Connector cannot be read from an Impala virtual warehouse.

Read the tables from a Hive virtual warehouse or using Impala queries in Data Hub.
