[jira] [Created] (DRILL-2245) Improve Drillbit resiliency

Chris Westin created DRILL-2245:
-----------------------------------

             Summary: Improve Drillbit resiliency
                 Key: DRILL-2245
                 URL: https://issues.apache.org/jira/browse/DRILL-2245
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
            Reporter: Chris Westin
            Assignee: Chris Westin


There are paths through WorkManager and Foreman that will allow a Drillbit to get wedged if there are failures. This can happen because events delivered via other threads will get stuck if Foreman throws an exception before it is accepting external events.

This is a call to do some general cleanup here and make drillbits more robust so that they don't hang when there are query failures.
