[jira] [Created] (FLINK-9827) ResourceManager may receive outdate report of slots status from task manager

shuai.xu created FLINK-9827:
-------------------------------

             Summary: ResourceManager may receive outdate report of slots status from task manager
                 Key: FLINK-9827
                 URL: https://issues.apache.org/jira/browse/FLINK-9827
             Project: Flink
          Issue Type: Bug
          Components: Cluster Management
    Affects Versions: 1.5.0
            Reporter: shuai.xu
            Assignee: shuai.xu


TaskExecutor will report its slot status to resource manager in heartbeat, but this is in a different thread with the main rpc  thread. So it may happen that rm request a slot from task executor but then receive a heartbeat saying the slot not assigned. This will cause the slot be freed and assigned again.
