             Summary: Cancel query that is in Planing state - user RPC thread of the foreman Drillbit will block waiting for query to finish planing
                 Key: DRILL-4680
                 URL: https://issues.apache.org/jira/browse/DRILL-4680
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 1.7.0
         Environment: 4 node cluster CentOS
            Reporter: Khurram Faraaz


Unfortunately, if you try to cancel a query that's still in planing, the user RPC thread of the foreman Drillbit will block waiting for the query to finish planing, this will cause any other query submitted to the same Drillbit to block as well. It's a known issue (actually a serious Drill  limitation).
