Kezhu Wang created FLINK-21821:
----------------------------------
Summary: StreamTask.cancelables was closed concurrent between task
canceler and task thread
Key: FLINK-21821
URL: https://issues.apache.org/jira/browse/FLINK-21821
Project: Flink
Issue Type: Improvement
Components: Runtime / Task
Affects Versions: 1.13.0
Reporter: Kezhu Wang
I think {{AbstractInvokable.cancel}} should only do flag things but not closing
staff. Otherwise task canceler and task thread will contend on these closing
tasks.
It is same for {{BatchTask.cancel}} which might be confirmed as one potential
cause for FLINK-21728.
