-------------------------------------
Summary: StreamingWithStateTestBase's subclasses might fail during
cleanup if sharing the state directory (through a common @TempDir)
Key: FLINK-33820
URL: https://issues.apache.org/jira/browse/FLINK-33820
Project: Flink
Issue Type: Bug
Reporter: Matthias Pohl
FLINK-33641 revealed an issue where StreamingWithStateTestBase implementing
test classes failed during cleanup due to some concurrency that's not fully
understood, yet (see [FLINK-33641
PR|https://github.com/apache/flink/pull/23914] discussion for more details).
FLINK-33641 provided a workaround for now that creates per-class temporary
folders. This Jira is about investigating why this of test failures actually
exists.
