Damian Guy created KAFKA-4516:
---------------------------------

             Summary: When a CachingStateStore is closed it should clear its associated NamedCache. Subsequent queries should throw InvalidStateStoreException
                 Key: KAFKA-4516
                 URL: https://issues.apache.org/jira/browse/KAFKA-4516
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 0.10.1.0
            Reporter: Damian Guy
            Assignee: Damian Guy
             Fix For: 0.10.2.0


When close is called on a CachingStateStore we don't release the memory it is using in the Cache. This could result in the cache being full of data that is redundant. We also still allow queries on the CachedStateStore even though it has been closed.
