>             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.
