[jira] [Created] (FLINK-16139) Co-location constraints are not reset on task recovery in DefaultScheduler

Zhu Zhu created FLINK-16139:
-------------------------------

             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.
