             Summary: Harden JobMaster#updateTaskExecutionState()
                 Key: FLINK-21735
                 URL: https://issues.apache.org/jira/browse/FLINK-21735
             Project: Flink
          Issue Type: Improvement
          Components: Runtime / Coordination
    Affects Versions: 1.13.0
            Reporter: Zhu Zhu


Currently JobMaster#updateTaskExecutionState() is very important to trigger task scheduling and recovery. We do not expect any exception to happen directly in its invocation, so I'd propose to wrap it with a try-catch to fail the JobMaster once any exception is caught. This can better expose the unexpected bugs.
