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

             Summary: Change SourceCoordinator to handle resetToCheckpoint() call after started.
                 Key: FLINK-18039
                 URL: https://issues.apache.org/jira/browse/FLINK-18039
             Project: Flink
          Issue Type: Sub-task
    Affects Versions: 1.11.0
            Reporter: Jiangjie Qin


Right now the SourceCoordinator assumes that {{resetToCheckpoint()}} is only called before {{start()}} is called. We need to change the SourceCoordinator to handle the case when {{resetToCheckpoint()}} is invoked after the SourceCoordinator has started.
