Hi team, I have raised PR's in branch-3 https://github.com/apache/hive/pull/4495 and branch-3.1 https://github.com/apache/hive/pull/4522 to provide JDK 11 support for Hive 3.x releases. This was already committed in Hive 2.3.9 which supports JDK11 now through this ticket - https://issues.apache.org/jira/browse/HIVE-22096. So it makes sense to backport the same to branch-3.x in Hive. Request someone in the community to review these tickets.
Thanks, Aman.
