----------------------------------------------

             Summary: ZK disconnect to foreman node results in hung query on client
                 Key: DRILL-2552
                 URL: https://issues.apache.org/jira/browse/DRILL-2552
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
    Affects Versions: 0.8.0
            Reporter: Ramana Inukonda Nagaraj
            Assignee: Chris Westin


Steps taken to recreate:
1. Startup drillbits on multiple nodes. (They all come up and form a 8 node cluster)
2. Start executing a long running query.
3. Use TCPKILL to kill all connections between foreman node and zookeeper port 5181. 

Drill seems to detect the node as gone and cancels the query but there is no communication
of this back to the client which is hanging.
