Sergey Shelukhin commented on HIVE-4242:
----------------------------------------
The patch sets the filter unconditionally. Should it rather change the config
setting or add a new one?
> Predicate push down should also be provided to InputFormats

> Currently, the push down predicate is only provided to native tables if the
> hive.optimize.index.filter configuration variable is set. There is no reason
> to prevent InputFormats from getting the required information to do predicate
> push down.
> Obviously, this will be very useful for ORC.
