-----------------------------------------
Summary: Multiple ResourceManagers register at JobManager in
standalone HA mode
Key: FLINK-3982
URL: https://issues.apache.org/jira/browse/FLINK-3982
Project: Flink
Issue Type: Bug
Components: ResourceManager
Affects Versions: 1.1.0
Reporter: Maximilian Michels
Assignee: Maximilian Michels
Priority: Minor
Fix For: 1.1.0
In HA mode, multiple ResourceManagers may register at the leading JobManager.
They register one after another at the JobManager. The last registering
ResourceManager stays registered with the JobManager. This only applies to
Standalone mode and doesn't affect functionality.
To prevent duplicate registration for the standalone ResourceManager, the
easiest solution is to only start registration when the leading JobManager runs
in the same ActorSystem as the ResourceManager. Other ResourceManager
implementations may also run independently of the JobManager.
