Hi, All. Thanks to your many many contributions, Apache Spark master branch starts to pass on JDK11 as of today. (with `hadoop-3.2` profile: Apache Hadoop 3.2 and Hive 2.3.6)
https://amplab.cs.berkeley.edu/jenkins/view/Spark%20QA%20Test%20(Dashboard)/job/spark-master-test-maven-hadoop-3.2-jdk-11/326/ (JDK11 is used for building and testing.) We already verified all UTs (including PySpark/SparkR) before. Please feel free to use JDK11 in order to build/test/run `master` branch and share your experience including any issues. It will help Apache Spark 3.0.0 release. For the follow-ups, please follow https://issues.apache.org/jira/browse/SPARK-24417 . The next step is `how to support JDK8/JDK11 together in a single artifact`. Bests, Dongjoon.
