[jira] [Created] (IMPALA-9531) Drop support for "dateless timestamps"

Csaba Ringhofer created IMPALA-9531:
---------------------------------------

             Summary: Drop support for "dateless timestamps"
                 Key: IMPALA-9531
                 URL: https://issues.apache.org/jira/browse/IMPALA-9531
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Csaba Ringhofer


Currently cast("15:42:00" as timestamp) doesn't return NULL, but it should, as the resulting timestamps are more or less useless:
- other fileformats than text do not support them
- most built-in unctions don't support them - even those where it could  make sense

IMPALA-5942 contains more details about these issues.
