Gopal V commented on HIVE-7231:
-------------------------------

[~leftylev]: HIVE-7231.5.patch has that clarified in hive-default.xml and with a default case
(64Mb stripe, 256Mb block = 3.2Mb padding tolerance per 256Mb block).

> Current ORC padding is not optimal because of fixed stripe sizes within block. The padding
overhead will be significant in some cases. Also padding percentage relative to stripe size
is not configurable.
