@omalley and @alanfgates . I'm trying to make Apache Spark 3.1 (scheduled on December 2020) to use Apache ORC 1.6.6. We need at least - ORC-669. Reduce breaking changes in ReaderImpl.java (this PR) - [[SPARK-33047][BUILD] Upgrade hive-storage-api to 2.7.2](https://github.com/apache/spark/pull/29923) The other stuffs I'm looking at are the followings - The ORC's case-insensitive predicate handling change (1.6.x returns more rows compared with 1.5.x). Although Spark can filter this, this may cause a performance regression. - `OrcTail` API change. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
