Relevant WARN logging: 2022-03-31 10:34:41,689 WARN [SpringApplicationShutdownHook] org.apache.kafka.streams.processor.internals.StateDirectory: stream-thread [SpringApplicationShutdownHook] Failed to delete state store directory of /kafka-streams-statestore/555b9965-95e3-4c92-b467-1d283428da5d/test-test-run-kpi for it is not empty Left over files in directory: * .lock * kafka-streams-process-metadata I'm not sure what the consequences of a unclean state cleanup are, but I would like to get rid of the Warning. I attached a bigger log extract and I've already patched the StateDirectory implementation which I'll try to contribute. -- This message was sent by Atlassian Jira (v8.20.1#820001)
