-------------------------------------
Summary: Complete requested slots in request order
Key: FLINK-13165
URL: https://issues.apache.org/jira/browse/FLINK-13165
Project: Flink
Issue Type: Sub-task
Components: Runtime / Coordination
Affects Versions: 1.9.0
Reporter: Till Rohrmann
Fix For: 1.9.0
When executing batch jobs with fewer slots than requested we should make sure
that the slot requests are being completed in the order in which they were
enqueued into the {{SlotPool}}. Otherwise we might risk that a consumer task
gets deployed before a producer causing a resource deadlock situation.
