-------------------------------------
Summary: Add fallback error handler to DefaultLeaderElectionService
Key: FLINK-32413
URL: https://issues.apache.org/jira/browse/FLINK-32413
Project: Flink
Issue Type: Sub-task
Components: Runtime / Coordination
Reporter: Matthias Pohl
The FLIP-285 work separated the driver lifecycle from the contender lifecycle.
Now, a contender can be removed but the driver could still be running. Error
could be produced on the driver's side. The {{DefaultLeaderElectionService}}
would try to forward the error to the contender. With not contender being
registered, the error would be swallowed.
We should add a fallback error handler for this specific case.
