Till Rohrmann created FLINK-9910:
------------------------------------
Summary: Non-queued scheduling failure sometimes does not return the slot
Key: FLINK-9910
URL: https://issues.apache.org/jira/browse/FLINK-9910
Project: Flink
Issue Type: Bug
Components: Distributed Coordination
Affects Versions: 1.5.1, 1.6.0, 1.7.0
Reporter: Till Rohrmann
Assignee: Till Rohrmann
Fix For: 1.5.2, 1.6.0
Similar to FLINK-9908, it can happen that in case of a non-queued scheduling failure a slot
is not properly returned to the {{SlotPool}}. The reason for the failure seems to be the exceptional
completion of the {{allocationFuture}} in {{Execution#scheduleForExecution}}.
