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)
