Till Rohrmann created FLINK-25533:
-------------------------------------
Summary: Preferred AllocationIDs are not respected when fulfilling
pending slot requests
Key: FLINK-25533
URL: https://issues.apache.org/jira/browse/FLINK-25533
Project: Flink
Issue Type: Bug
Components: Runtime / Coordination
Affects Versions: 1.14.2, 1.13.5, 1.15.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Fix For: 1.15.0
In order to make best use of local recovery, we have to forward the set of
preferred allocations to the {{DeclarativeSlotPoolBridge}} where new slots are
matched with pending slot requests. At the moment this is not the case and this
means that whenever we try to recover locally while not having all slots
available, we might do wrong scheduling decisions.
In order to improve the situation, I propose to forward the set of preferred
allocations to the {{DeclarativeSlotPoolBridge}}.
