Naveen Gangam commented on HIVE-19933:
--------------------------------------
[~belugabehr] I think it makes to do so when there is just one partition as you
said. My only [mild] worry is that it makes it inconsistent with the behavior
when there are multiple partitions. Will take a deeper look to understand the
behavior in all scenarios and make a fix.

> ALTER TABLE web_logsz DROP PARTITION (`date`='xyz')
> -- SemanticException [Error 10001]: Table not found web_logsz
> ALTER TABLE web_logs DROP PARTITION (`date`='xyz')
> -- Success.
> {code}
> There is no 'xyz' partition for the 'date' column. To make this more
> consistent, the query should fail if the user tries to drop a partition that
> does not exist
