-------------------------------------------
> Implicit cast fails with {const INT} BETWEEN FLOAT and INT

> Key: IMPALA-8054
> URL: https://issues.apache.org/jira/browse/IMPALA-8054
> Project: IMPALA
> Issue Type: Bug
> Components: Frontend
> Affects Versions: Impala 3.2.0
> Reporter: Greg Rahn
> Assignee: Peter Rozsa
> Priority: Major
>
> In the following query the literal number 10 needs to be compared to two
> different types: INT and FLOAT, but Impala fails to make the implicit cast
> for the FLOAT.
> The predicates should be
> {noformat}
> predicates: (cast(10 as float) >= col4) AND (10 <= col3)
> {noformat}
> *Test cases:*
> {noformat}
> sql> describe tab4

> sql> SELECT * FROM tab4 WHERE NULL BETWEEN CAST ( NULL AS INTEGER ) AND col4
