> After we get the new interface to get rid of filters predicate-push-downed which are
processed in datasource-level (https://github.com/apache/spark/pull/9399), it dose not push
down filters for ORC.
> This is because at {{DataSourceStrategy}}, it is classified to scanning non-partitioned
HadoopFsRelation, and all the filters are treated as unhandled filters.
> Also, since ORC does not support to filter fully record by record but instead rough results
came out, the filters for ORC should not go to unhandled filters.
