[jira] [Updated] (IMPALA-12042) Invalid casts in set operations calculation
[ https://issues.apache.org/jira/browse/IMPALA-12042?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Peter Rozsa updated IMPALA-12042:
---------------------------------
Description:
Invalid implicit casts are produced when a set operation contains transitive compatibility, for example:
{code:java}
values (true), (123), (111.0){code}
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
{code:java}
IllegalStateException: cast BOOLEAN to DECIMAL(4,1){code}
was:
