Bug Fixes

Flink

• ODP-7676: Resolved an issue where Flink's Hive 4.1.0 DataConnector used incorrect Thrift API signatures, which could cause connector calls to fail. The DataConnector now matches Hive 4.1.0's Thrift signatures.

Hadoop

Hive

• ODP-1672 | ODP-2217: Resolved an issue where upgrading Hive from 3.1.4 to 4.0.0 could fail partway through the schema upgrade. The upgrade now completes correctly and returns accurate responses.
