Eric Payne commented on YARN-9931: ---------------------------------- [~cane], I'm a little reluctant to add features into the YARN framework that could possibly be doneoutside of it. Wouldn't it be possible to add a JVM shutdown hook to the class running in the container's JVM? > Support run script before kill container > ---------------------------------------- > > Key: YARN-9931 > URL: https://issues.apache.org/jira/browse/YARN-9931 > Project: Hadoop YARN > Issue Type: Improvement > Components: nodemanager > Reporter: zhoukang > Assignee: zhoukang > Priority: Major > > Like node health check script.
