-------------------------------------------
Hi [~groot],
Before we upgraded our HDFS cluster from Java8 to Java11, we did some
performance tests using Dynamometer and didn't see any performance degradation.
We have been using HDFS cluster with Java11 for over two years, and we haven't
seen any significant degradation due to Java11. We haven't tried Java11 and
have used Java8 for YARN.
