   I also have a problem about `cancel query`, the scenario is as follows:
   1. I execute a big query which will runs 1 minute .the timeout is default 5 minutes, after it runs 3 second, we cancel it through `curl -X DELETE "http://broker:8082/druid/v2/queryid"` and it will be canceled success and all historical nodes will cancel it success too.
   2. but if it runs more than 10 secnods , after we cancel it with the DELETE API,  we find the query will be canceled ,but not all historical nodes cancel it too.
   
   for 2,  because  `futures`  control `segment query`, so can't be canceled in `Merging`
