Hi all, We are having an issue where Flink Application Master is unable to automatically restart Flink job after its delegation token has expired.
We are using Flink 1.11 with YARN 3.1.1 in single job per yarn-cluster mode. We have also add valid keytab configuration and taskmanagers are able to login with keytabs correctly. However, it seems YARN Application Master still use delegation tokens instead of the keytab. Any idea how to resolve this would be much appreciated. Thanks Kien
