-------------------------------------
Summary: EmbeddedHaServices is not made for recovery on a single
instance
Key: FLINK-26630
URL: https://issues.apache.org/jira/browse/FLINK-26630
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Affects Versions: 1.15.0
Reporter: Matthias Pohl
{{EmbeddedHaServices}} (and {{EmbeddedHaServicesWithLeadershipControl}})
provide leader election functionality to work on a single JVM. In FLINK-25235
we introduced the re-instantiation of {{HighAvailabilityServices}} per
{{JobManager}} (i.e. {{DispatcherResourceManagerComponent}}) to be able to
close the HighAvailabilityServices during the shutdown of a JM and not only at
the end of the HA cluster to get closer to a production environment where each
JM has its own HAServices instance as well (that became crucial as part of the
work of FLINK-24038 which revokes the leadership when it closes the HAServices
during a JM shutdown).
