Subject [jira] [Created] (DRILL-4766) FragmentExecutor should use EventProcessor and avoid blocking rpc threads
Date Tue, 05 Jul 2016 20:09:11 GMT
Deneche A. Hakim created DRILL-4766:
---------------------------------------

             Summary: FragmentExecutor should use EventProcessor and avoid blocking rpc threads
                 Key: DRILL-4766
                 URL: https://issues.apache.org/jira/browse/DRILL-4766
             Project: Apache Drill
          Issue Type: Improvement
          Components: Execution - Flow
    Affects Versions: 1.7.0
            Reporter: Deneche A. Hakim
            Assignee: Deneche A. Hakim
            Priority: Minor


Currently, rpc thread can block when trying to deliver a cancel or early termination message
to a blocked fragment executor.

Foreman already uses an EventProcessor to avoid such scenarios. FragmentExecutor could be
improved to avoid blocking rpc threads as well
