I sincerely appreciate, Alan, for a quick positive response. Thanks Yuming for quickly starting to work on that.
For quick updates: - Seems Yuming already started to investigate it at https://issues.apache.org/jira/browse/HIVE-22096 - I will try to reach him and get synced. (He works in a different company and lives in a different country from me so some delays are expected) - Spark side, it's being investigated under https://issues.apache.org/jira/browse/SPARK-28684 - .. and .. actually I am now synced with Yuming, almost of all tests pass only with HIVE-22096 Alan, would you mind if I ask to make a snapshot after HIVE-22096 fix if it makes sense? Sounds like, in his local, almost all Spark test cases pass except one test case with HIVE-22096 (with JDK 11). Looks like he wants to verify via Spark CI as well to show official test results to show up which can be easily done if there's a snapshot. 2019년 8월 10일 (토) 오전 6:35, Alan Gates <alanfga...@gmail.com>님이 작성: > I think it's fine to backport this and do a release.
