> Key: FLINK-10386
> URL: https://issues.apache.org/jira/browse/FLINK-10386
> Project: Flink
> Issue Type: Sub-task
> Components: TaskManager
> Affects Versions: 1.7.0
> Reporter: TisonKun
> Assignee: TisonKun
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.7.0
>
>
> After a discussion
> [here|https://github.com/apache/flink/commit/0735b5b935b0c0757943e2d58047afcfb9949560#commitcomment-30584257]
> with [~trohrm...@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}}.
