-------------------------------------------

             Summary: Support waiting for required resources in DefaultScheduler during job restart
                 Key: FLINK-31458
                 URL: https://issues.apache.org/jira/browse/FLINK-31458
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
    Affects Versions: 1.15.3
            Reporter: Aleksandr Pilipenko


Currently Flink support [waiting for required resources to become available|https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/config/#jobmanager-adaptive-scheduler-resource-stabilization-timeout] during job restart only while using adaptive scheduler.
On the other hand, if cluster is using default scheduler and there is not enough slots available - restart attempts will fail with `NoResourceAvailableException` until resource requirements are satisfied.
