Brock Noland commented on HIVE-5700:
------------------------------------

[~sershe] - in my setup, I have a pre-upgrade table with date partitions in the 
form of {{20141218}}. Sure enough after upgrading {{PARTITION.PART_NAME}} is 
not updated and as such I cannot do operations like modify the partitions 
location. If I manually fix {{PARTITION.PART_NAME}} I am able to use the 
partition.

Furthermore we get even more interesting results on postgres. I am setting up 
an environment to reproduce this and will share additional details tomorrow.

> 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.
