>             Project: Flink
>          Issue Type: Sub-task
>          Components: Client
>    Affects Versions: 1.5.0
>            Reporter: Till Rohrmann
>            Assignee: Till Rohrmann
>              Labels: flip-6
>             Fix For: 1.5.0
>
>
> Currently, the {{CliFrontend}} sends the command for disposing a savepoint. 
> In order to better abstract this functionality we should move it to the 
> {{ClusterClient}}. That way we can have different implementations of the 
> {{ClusterClient}} (Flip-6 and old code) which are used by the same 
> {{CliFrontend}}.
