> Replacing vertexExecution in ScheduledUnit with executionVertexID
> -----------------------------------------------------------------

> Key: FLINK-16180
> URL: https://issues.apache.org/jira/browse/FLINK-16180
> Project: Flink
> Issue Type: Sub-task
> Components: Runtime / Coordination
> Affects Versions: 1.11.0
> Reporter: Zhu Zhu
> Assignee: Zhu Zhu
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.11.0
>
>
> {{ScheduledUnit#vertexExecution}} is nullable but {{ProgrammedSlotProvider}}
> requires it to be non-null to work. This makes {{ProgrammedSlotProvider}} not
> able to be used by new scheduler tests since {{vertexExecution}} is never set
> in the new scheduler code path. It blocks us from reworking tests which are
> based legacy scheduling to base on the new scheduler.
> I would propose to replace the nullable vertexExecution with a non-null
> executionVertexID.
> This change would not break anything since {{vertexExecution}} is mainly used
> by {{ProgrammedSlotProvider}} for testing. {{ProgrammedSlotProvider}} uses it
> to retrieve the JobVertexID and subtaskIndex.
> The only other place where {{ScheduledUnit#vertexExecution}} is used is to
> log the involved task for slot allocation in
> {{SchedulerImpl#allocateSlotInternal(...)}}. The log is problematic at the
> moment with the new scheduler since the vertexExecution is null. This change
> can fix the problematic log.
> This change would also fix a NPE issue reported in FLINK-16145.
