[jira] [Created] (IMPALA-12042) Invalid casts in set operations calculation

Peter Rozsa created IMPALA-12042:
------------------------------------

             Summary: Invalid casts in set operations calculation
                 Key: IMPALA-12042
                 URL: https://issues.apache.org/jira/browse/IMPALA-12042
             Project: IMPALA
          Issue Type: Bug
          Components: fe
    Affects Versions: Impala 4.3.0
            Reporter: Peter Rozsa


Invalid implicit casts are produced when a set operation contains transitive compatibility, for example: ```values (true), (123), (111.0)``` where boolean(true) is compatible with tinyint(123) and tinyint is compatible with decimal(111.0) but boolean is not compatible with decimal nonetheless 'castToSetOpCompatibleTypes' produces decimal as a compatible type.

If the condition described above exists, FE fails with ```IllegalStateException: cast BOOLEAN to DECIMAL(4,1)```
