---------------------------------------
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.
