Sergey Shelukhin commented on HIVE-5700:
----------------------------------------

I was hoping to avoid writing Derby upgrade script... it;s not DB structure - 
do people really need to upgrade derby? Hmm.

As for negative tests, the problem is that date validation on JDK6 is going to 
kick in first and reject the date literal before this code executes... the only 
way to allow it is to run JDK7, for example. Let me think about more isolated 
test

> enforce single date format for partition column storage

> "inspired" by HIVE-5286.
> Partition column for dates should be stored as either integer, or as fixed 
> representation e.g. yyyy-mm-dd. External representation can remain varied as 
> is.
