     *    have been created with the right number of partitions.
     *
     * 2. using TaskAssignor to assign tasks to consumer clients.
     *    - Assign a task to a client which was running it previously.
     *      If there is no such client, assign a task to a client which has its valid local state.
     *    - A client may have more than one stream threads.
     *      The assignor tries to assign tasks to a client proportionally to the number of threads.
     *    - We try not to assign the same set of tasks to two different clients
     *    We do the assignment in one-pass. The result may not satisfy above all.
     *
