Dongjoon Hyun 83c008762a [SPARK-23456][SPARK-21783] Turn on native ORC impl and PPD by default ... ## What changes were proposed in this pull request? Apache Spark 2.3 introduced `native` ORC supports with vectorization and many fixes. However, it's shipped as a not-default option. This PR enables `native` ORC implementation and predicate-pushdown by default for Apache Spark 2.4. We will improve and stabilize ORC data source before Apache Spark 2.4. And, eventually, Apache Spark will drop old Hive-based ORC code. ## How was this patch tested? Pass the Jenkins with existing tests. Author: Dongjoon Hyun <dongjoon@apache.org> Closes #20634 from dongjoon-hyun/SPARK-23456.		2018-02-20 09:14:56 -08:00
