             Summary: RocksDB segments not removed when store is closed causes re-initialization to fail
                 Key: KAFKA-6360
                 URL: https://issues.apache.org/jira/browse/KAFKA-6360
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 1.1.0
            Reporter: Damian Guy
            Assignee: Damian Guy
