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

             Summary: StreamTask closeAllOperators stuck
                 Key: FLINK-20649
                 URL: https://issues.apache.org/jira/browse/FLINK-20649
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Task
    Affects Versions: 1.12.0
            Reporter: weiyunqing
         Attachments: image-2020-12-17-17-57-41-680.png

When a StreamTask exits due to an internal exception, the StreamTask does not use an asynchronous thread to closeAllOperators or set a timeout. The StreamTask will be stuck here (no upstream and downstream scenarios)
