> Components: Connectors / Hive

> Hive NVL() function has many issues like
> [HIVE-25193|https://issues.apache.org/jira/browse/HIVE-25193] and it is
> retired [HIVE-20961|https://issues.apache.org/jira/browse/HIVE-20961]. Our
> internal hive distribution has the fix for HIVE-20961. With this fix, Flink
> Build is failing with below as there is no more GenericUDFNvl in Hive. This
> needs to be replaced with GenericUDFCoalesce.
