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

             Summary: SourceCoordinator should avoid fail job multiple times.
                 Key: FLINK-19535
                 URL: https://issues.apache.org/jira/browse/FLINK-19535
             Project: Flink
          Issue Type: Bug
          Components: Connectors / Common
    Affects Versions: 1.11.2
            Reporter: Jiangjie Qin


Currently the {{SourceCoordinator}} may invoke {{SourceCoordinatorContext#failJob()}} multiple times from the same instance. This may cause the job to failover multiple times unnecessarily. The {{SourceCoordinator}} should instead just fail the job once.
