[jira] [Created] (KAFKA-3710) MemoryOffsetBackingStore creates a non-daemon thread that prevents clean shutdown

----------------------------------

             Summary: MemoryOffsetBackingStore creates a non-daemon thread that prevents clean shutdown
                 Key: KAFKA-3710
                 URL: https://issues.apache.org/jira/browse/KAFKA-3710
             Project: Kafka
          Issue Type: Bug
          Components: KafkaConnect
    Affects Versions: 0.9.0.1
            Reporter: Peter Davis
            Assignee: Ewen Cheslack-Postava


MemoryOffsetBackingStore creates an ExecutorService but MemoryOffsetBackingStore.stop() fails to call executor.shutdown().  This creates a zombie non-daemon thread which prevents clean shutdown when running a StandaloneHerder embedded in another application.

Note that FileOffsetBackingStore extends MemoryOffsetBackingStore so is also affected.
