   > Interesting. AFAIT, this shouldn't happen if the task successfully handed off all created segments. Also, this NPE doesn't do anything with the task status. It should be just a query failure. I suspect the task failed to hand off segments for some reason which made the task failed. Do you see anything interesting in the task logs?
   
   yes, this NPE could cause query failed, how to fixed it ? @jihoonson
