---------------------------------------
Summary: taskmanager.jvm-exit-on-oom doesn't work reliably with
YARN
Key: FLINK-13472
URL: https://issues.apache.org/jira/browse/FLINK-13472
Project: Flink
Issue Type: Bug
Components: core
Affects Versions: 1.6.3
Reporter: Pawel Bartoszek
I have added *taskmanager.jvm-exit-on-oom* flag to the task manager starting
arguments. During my testing (simulating oom) I noticed that sometimes YARN
containers were still in RUNNING state even though they should haven been
killed on OutOfMemory errors with the flag on.
I could find RUNNING containers with the last log lines like this.
{code:java}
2019-07-26 13:32:51,396 ERROR org.apache.flink.runtime.taskmanager.Task

Does YARN make it tricky to forcefully kill JVM after OutOfMemory error?
