4Apache drill cannot read ORC. But Apache Spark has been optimized for ORC support. Check [this](https://hortonworks.com/blog/bringing-orc-support-into-apache-spark/) out for further info – Nayantara Jeyaraj Mar 20 '18 at 11:07

Drill can read ORC format files via the Hive plugin. If you have a Hive table with underlying data stored as ORC, try and configure the Hive storage plugin in Drill [1]. And then you can attempt to query the table in Hive from Drill [2].
