Gopal V commented on HIVE-7231:
-------------------------------
The approach results in stray writes across the stripe boundaries.
I think this approach needs to be revisited to disconnect the HDFS block size
from the ORC stripe size.
The stripe size needs to be a factor of the HDFS block size, but the fraction
should not remain at 0.5x.

> 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.
