> 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
> Priority: Major
> 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.
