Subject Re: No zero ( 2 ) exit code on k8s StandaloneJobClusterEntryPoint when save point with cancel...
Date Tue, 23 Apr 2019 18:01:09 GMT
Though looking at
https://github.com/apache/flink/blob/master/flink-runtime/src/main/java/org/apache/flink/runtime/resourcemanager/StandaloneResourceManager.java#L88
it
does seem that the last log . is expected.

Not sure what part is hanging... I have more logs I can share...
