[jira] [Created] (IMPALA-6415) Document breaking change of alias and ordinal substitution

Zoltán Borók-Nagy created IMPALA-6415:
-----------------------------------------

             Summary: Document breaking change of alias and ordinal substitution
                 Key: IMPALA-6415
                 URL: https://issues.apache.org/jira/browse/IMPALA-6415
             Project: IMPALA
          Issue Type: Documentation
          Components: Docs
            Reporter: Zoltán Borók-Nagy


IMPALA-5191 changed the way how Impala handles aliases and ordinals.

Impala no longer performs alias substitution in the subexpressions of GROUP BY, HAVING, and ORDER BY to be more standard conformant.

We need to update the documentation regarding to the new behavior.
