Hi folks, Wanted to start a devlist thread to discuss removal of JDK 17 in favor of JDK 21/25 as supported runtimes in Druid 38. The PR for this change is here: https://github.com/apache/druid/pull/19304. Upgrading to Hadoop 3.5 clients enabled <https://hadoop.apache.org/docs/r3.5.0/> the use of JDK 21 and, from what I can tell, contains SecurityManager patches that unblock Druid's usage of JDK 25.
Best, Jesse
