陈梓立 created FLINK-10386:
---------------------------

             Summary: Remove legacy class TaskExecutionStateListener
                 Key: FLINK-10386
                 URL: https://issues.apache.org/jira/browse/FLINK-10386
             Project: Flink
          Issue Type: Improvement
          Components: TaskManager
    Affects Versions: 1.7.0
            Reporter: 陈梓立
            Assignee: 陈梓立
             Fix For: 1.7.0


After a discussion [here|https://github.com/apache/flink/commit/0735b5b935b0c0757943e2d58047afcfb9949560#commitcomment-30584257] with [~trohrmann@apache.org]. I start to analyze the usage of {{ActorGatewayTaskExecutionStateListener}} and {{TaskExecutionStateListener}}.

In conclusion, we abort {{TaskExecutionStateListener}} strategy and no any component rely on it. Instead, we introduce {{TaskManagerActions}} to take the role for the communication of {{Task}} with {{TaskManager}}. No one except {{TaskManager}} should directly communicate with {{Task}}. So it can be safely remove legacy class {{TaskExecutionStateListener}}.
