[jira] [Created] (FLINK-32788) SpeculativeScheduler do not handle allocate task errors when schedule speculative tasks may causes resource leakage.

Junrui Li created FLINK-32788:
---------------------------------

             Summary: SpeculativeScheduler do not handle allocate task errors when schedule speculative tasks may causes resource leakage.
                 Key: FLINK-32788
                 URL: https://issues.apache.org/jira/browse/FLINK-32788
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.18.0
            Reporter: Junrui Li


When the SpeculativeScheduler allocates slots for speculative tasks, exceptions may occur, but there is currently no exception handling mechanism in place. This can lead to resource leakage (such as FLINK-32768) when errors occur. In such cases, a fatalError should be triggered.
