[jira] [Created] (FLINK-28473) JobManager restart/failover doesn't trigger local recovery on TaskManagers

Levani Kokhreidze created FLINK-28473:
-----------------------------------------

             Summary: JobManager restart/failover doesn't trigger local recovery on TaskManagers
                 Key: FLINK-28473
                 URL: https://issues.apache.org/jira/browse/FLINK-28473
             Project: Flink
          Issue Type: Bug
          Components: Runtime / State Backends, Runtime / Task
    Affects Versions: 1.15.1, 1.15.0
            Reporter: Levani Kokhreidze


Hi! While experimenting with local recovery feature (Flink 1.15.1) I noticed that if JobManager is restarted TaskManagers always recover from Remote ({{{}IncrementalRemoteKeyedStateHandle{}}}). While if I restart task managers, local recovery is triggered.
 
Setup: * HA setup with Zookeeper and S3 remote storage.
 * JobManager runs as StatefulSet with PersistentVolume. Both {{process.jobmanager.working-dir}} and {{jobmanager.resource-id}} are correctly configured.
 * TaskManagers run as StatefulSets with PersistentVolume. Both {{process.taskmanager.working-dir}} and {{taskmanager.resource-id}} are correctly configured.
