[jira] [Created] (DRILL-3142) In case of a quick kill and start of drillbits running query hangs

Ramana Inukonda Nagaraj created DRILL-3142:
----------------------------------------------

             Summary: In case of a quick kill and start of drillbits running query hangs
                 Key: DRILL-3142
                 URL: https://issues.apache.org/jira/browse/DRILL-3142
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
    Affects Versions: 1.0.0
            Reporter: Ramana Inukonda Nagaraj
            Assignee: Chris Westin


Steps to repro:
1) Run a long running query.
2) Kill one of the non foreman drillbits.
3) Start the killed drillbit immediately. 

Sporadically the running query hangs on both server and client. I suspect this has to do with the fact that the kill and start was so quick that the drillbit was never detected as failed. 

The fix would involve keeping some relevant information of the running drillbit(maybe pid) and checking if its the same drillbit which is working and not a new fresh drillbit.
