haiboself commented on issue #23944: [SPARK-26932][DOC]Hive 2.1.1 cannot read ORC table created by Spark 2.4.0 in default URL: https://github.com/apache/spark/pull/23944#issuecomment-469167749 @dongjoon-hyun Thanks for your proposal, I would like to change to following content, is it right? ``` - Since Spark 2.4, Spark maximizes the usage of a vectorized ORC reader for ORC files by default. To do that, `spark.sql.orc.impl` and `spark.sql.orc.filterPushdown` change their default values to `native` and `true` respectivelyi. Which cause Hive 2.1.1 cannot read ORC table created by Spark 2.4. As for Hive, Hive 2.3.0+ is generating ORC tables which Hive 2.1.1 cannot read. To set `hive` to `spark.sql.orc.impl` restores the previous behavior. ```
