LGTM, there's some leftover constants that should be removed, maybe rename a config, and one typo (I think). Also, this is my first time looking into the KsStateStoreTest.java, @big-andy-coates what is this line doing if the timeout variable isn't being used in the test?

  @Rule
  public final Timeout timeout = Timeout.seconds(10);

Just 1 more thing, based on the issue you filed. You can make the call.
LGTM otherwise.

  public final Timeout timeout = Timeout.seconds(10);

That will cause the test to fail after 10 seconds if it hasn't completed.
