-----------------------------------
>From javadoc, it seems caller should use stringPropertyNames() to get a set of
>property names instead of calling keys() or keySet().
> SerDes that do not inherit AbstractSerDe do not get table properties during
> initialize()

> Looks like this may have been introduced during HIVE-6835. During
> initialize(), 3rd party SerDes which do not inherit AbstractSerDe end up
> getting a Properties object created by
> SerDeUtils.createOverlayedProperties(). This properties object receives the
> table properties as defaults. So looking up a key by name will yield the
> default value, but a call like getKeys() will not show any of the table
> properties.
