[GitHub] [orc] dongjoon-hyun commented on issue #1237: The result is strange when casting `string` to `date` in ORC reading via spark (Schema Evolution)

   1. First, may I ask why you cannot follow the community recommendation (1), @sinkinben ?
   2. Second, for your question, that's an independent question because `spark.sql.orc.impl=hive` is not Apache ORC code. It's Apache Spark code before Apache ORC adoption. You can file an Apache Spark JIRA issue for further investigation in Apache Spark community. I guess it will goes to Apache Hive `HiveDecimalWritable` or related classes in the end.
