> URL: https://issues.apache.org/jira/browse/FLINK-29590
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Hive
> Affects Versions: 1.16.0
> Reporter: luoyuxia
> Priority: Major
> Labels: pull-request-available

> in FLINK-26474, we try to fold constant, but it brings a issue that the
> folded constant like `Double.NAN` and no-primitive type can't be convert
> into calcite literal in method `HiveParserRexNodeConverter#convertConstant`.
> For example, the following code will throw an exception
> "org.apache.hadoop.hive.ql.parse.SemanticException: NaN" in method
> `HiveParserRexNodeConverter#convertConstant`
> {code:java}
> // hive dialect
> SELECT asin(2); {code}
> To fix it, we need to figure out such case and then not to fold constant .
>
> in FLINK-27017, we use Hive's `GenericUDFOPDivide` to do divide for better
> compatibility, but it bring a issue that when use a int/long literal as
> divisor, the result type passed and inferred type may not match.
> The fix it, we need to make the result type match the inferred type.
