Mass Dosage commented on SPARK-29245:
-------------------------------------
I have been working with the Hive community to get a Hive 2.3.7 release out
which should resolve this issue and allow the usage of Hive libraries on JDK
>=9. A release candidate has been created (you can test it out if you want -
https://repository.apache.org/content/repositories/orgapachehive-1100/) and
here is the discussion on the Hive dev list where a release has been proposed -
