[jira] [Created] (FLINK-23892) FineGrainedSlotManager is not sending signal for lacking resources

Chesnay Schepler created FLINK-23892:
----------------------------------------

             Summary: FineGrainedSlotManager is not sending signal for lacking resources
                 Key: FLINK-23892
                 URL: https://issues.apache.org/jira/browse/FLINK-23892
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
            Reporter: Chesnay Schepler
             Fix For: 1.14.0


When the FineGrainedSlotManager is used and resource requirements have been explicitly configured, then if the requirements exceed the amount of available resources the slot manager will try to allocate as many slots as possible but never inform the JM about lack of resources.

This causes the job to stall indefinitely.
