   Quick check, are you sure all your HiveTableOperations objects are being finalized? The SingleThreadedExecutor service should get shut down during the finalizer as long as there are no running tasks (which there shouldn't be after the commit is done)
   
   ```java
       public static ExecutorService newSingleThreadExecutor() {
           return new FinalizableDelegatedExecutorService
               (new ThreadPoolExecutor(1, 1,
                                       0L, TimeUnit.MILLISECONDS,
                                       new LinkedBlockingQueue<Runnable>()));
   ```
