Dongjoon Hyun f44ba910f5 [SPARK-16060][SQL] Support Vectorized ORC Reader ... ## What changes were proposed in this pull request? This PR adds an ORC columnar-batch reader to native `OrcFileFormat`. Since both Spark `ColumnarBatch` and ORC `RowBatch` are used together, it is faster than the current Spark implementation. This replaces the prior PR, #17924. Also, this PR adds `OrcReadBenchmark` to show the performance improvement. ## How was this patch tested? Pass the existing test cases. Author: Dongjoon Hyun <dongjoon@apache.org> Closes #19943 from dongjoon-hyun/SPARK-16060.		2018-01-09 21:48:14 +08:00
