----------------------------------
Summary: Thread leak in RocksDBStateUploader
Key: FLINK-22886
URL: https://issues.apache.org/jira/browse/FLINK-22886
Project: Flink
Issue Type: Bug
Components: Runtime / State Backends
Affects Versions: 1.12.4, 1.13.1, 1.11.3
Reporter: Jiayi Liao
{{ExecutorService}} in {{RocksDBStateUploader}} is not shut down, which may
leak thread when tasks fail.
BTW, we should name the thread group in {{ExecutorService}}, otherwise what we
see in the stack, is a lot of threads named with "pool-{x}-thread-{y}".
