Description

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.
