Till Rohrmann created FLINK-15691:
-------------------------------------
Summary:
TaskExecutorPartitionLifecycleTest#runInTaskExecutorThreadAndWait does not run
in main thread
Key: FLINK-15691
URL: https://issues.apache.org/jira/browse/FLINK-15691
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination, Tests
Affects Versions: 1.9.1, 1.10.0
Reporter: Till Rohrmann
Fix For: 1.11.0
The method
{{TaskExecutorPartitionLifecycleTest#runInTaskExecutorThreadAndWait}} does not
run the given runnable in the {{TaskExecutors}} main thread. Instead it will
run it in an arbitrary thread of the {{RpcService}}.
The reason why this does not cause test instabilities is that we execute
operations which don't cause race conditions. However, in order to avoid
spreading false friends I would suggest to get rid of this pattern. Moreover, I
would question whether {{TaskExecutorPartitionLifecycleTest}} really needs
access to the {{TaskExecutors}} internal state. I believe there is an easy way
using the {{TaskExecutors}} public API to implement the tests.
