             Summary: Drillbit while sending control message to itself creates a connection instead of submitting locally
                 Key: DRILL-6255
                 URL: https://issues.apache.org/jira/browse/DRILL-6255
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
    Affects Versions: 1.12.0
            Reporter: Sorabh Hamirwasia
            Assignee: Sorabh Hamirwasia
             Fix For: 1.14.0


With the new shutdown feature introduced in 1.12, there is a state introduced in DrillbitEndpoint. Due to this the equality check happening [here|https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/work/foreman/FragmentsRunner.java#L256] will result in false and hence the fragments supposed to be scheduled on Foreman will be treated as remote fragments and a connection will be created to schedule it. The equality check is false because localEndpoint state is STARTUP whereas state in assigned Drillbit is ONLINE.

I guess now we should update the equality check to verify just for address and control port to be same between assigned and local Drillbit endpoint. A test can be added for this based on _sys.memory_ table since that guarantees scheduling minor fragments on each Drillbit node.
