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.
