[jira] [Created] (FLINK-32413) Add fallback error handler to DefaultLeaderElectionService

Matthias Pohl created FLINK-32413:
-------------------------------------

             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.
