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

             Summary: PrelFinalizable.SHUTTLE can causes ArrayIndexOutOfBoundsException when
multiple queries are run concurrently
                 Key: DRILL-3809
                 URL: https://issues.apache.org/jira/browse/DRILL-3809
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
            Reporter: Deneche A. Hakim
            Assignee: Jinfeng Ni


{{PrelFinalizable.SHUTTLE}} is a static instance {{RelShuttleImpl}}, and because {{RelShuttleImpl}}
contains a state (a {{List<RelNode>}}) this can cause issues when multiple queries are
run concurrently.
