      Description

      The query does not return even though Fragment 0:0 reports a state change from RUNNING -> FINISHED

       

      Following is the jstack output of the Frag0:0.

      • From the code, it seems that RuntimeFilterSink.close is stuck at

       

      while (!asyncAggregateWorker.over.get()) {
       try
      { Thread.sleep(100); }
      catch (InterruptedException e)
      { logger.error("interrupted while sleeping to wait for the aggregating worker thread to exit", e); }
      }
      

      This is because AsyncAggregateWorker exits due to the following exception, before it could set asyncAggregateWorker.over is set to false.
