Since the IOManager add shutdown hook to clean up the files, should
IOManagerAsync#isProperlyShutDown need to call super.isProperlyShutDown ?
> Temporary channel files are not properly deleted when Flink is terminated

> Project: Flink
> Issue Type: Bug
> Components: TaskManager
> Affects Versions: 0.8, 0.9
> Reporter: Till Rohrmann
> Assignee: Ufuk Celebi
>
> The temporary channel files are not properly deleted if the IOManager does
> not shut down properly. This can be the case when the TaskManagers are
> terminated by Flink's shell scripts.
> A solution could be to store all channel files of one TaskManager in a
> uniquely identifiable directory and to register a shutdown hook which deletes
> this file upon termination.
