---------------------------------------
Summary: RPC Serialization failure when multiple job managers
Key: FLINK-25837
URL: https://issues.apache.org/jira/browse/FLINK-25837
Project: Flink
Issue Type: Bug
Affects Versions: 1.14.3
Reporter: Matthew McMahon
I'm using 1.14.3 with the Lyft FlinkK8sOperator to run the cluster.
Previously with 1.10.1 I had no problems, but now it seems when I have multiple
Job Managers deployed, I am continually seeing this error, that prevents the
Jobs from starting.
