> Key: FLINK-28287
> URL: https://issues.apache.org/jira/browse/FLINK-28287
> Project: Flink
> Issue Type: Improvement
> Affects Versions: 1.14.5, 1.15.1
> Reporter: JieFang.He
> Priority: Major
>
> TaskManagerRunner has a close method，but did not call when it stop.
> Some resources in TaskManagerRunner come with ShutdownHook, but some
> resources do not, such as rpcSystem, which causes the temporary file
> flink-rpc-akka_*.jar to not be deleted when stop.
> Should TaskManagerRunner need a ShutdownHook to call the close method to
> release all resources
