Dongjoon Hyun commented on SPARK-33295:
---------------------------------------

Hi, [~jaanai]. Yes. I've been working on that and it's ready for Apache Spark 
`sql/core` module. 
- ORC-669
- ORC-670
- ORC-671
- ORC-676
- ORC-677

However, it turns out that Apache ORC broke many things at Apache Hive still. 
So, it doesn't work with Apache Spark `sql/hive` and `sql/hive-thriftserver` 
module.

>  Upgrade ORC to 1.6.1
