             Summary: Co-location constraints are not reset on task recovery in 
DefaultScheduler
                 Key: FLINK-16139
                 URL: https://issues.apache.org/jira/browse/FLINK-16139
             Project: Flink
          Issue Type: Bug
          Components: Runtime / Coordination
    Affects Versions: 1.10.0
            Reporter: Zhu Zhu
            Assignee: Zhu Zhu
             Fix For: 1.10.1, 1.11.0


The colocation constraints are not reset on task recovery, which may lead to 
task recovery failures when allocating slots.
We should reset the colocation constraints before resetting vertices, just like 
what we do in the legacy scheduler.
