>             Project: Flink
>          Issue Type: Improvement
>          Components: Client
>    Affects Versions: 1.1.0
>            Reporter: Till Rohrmann
>            Assignee: Andrea Sella
>            Priority: Minor
> At the moment there is no other way than the environment variable 
> FLINK_CONF_DIR to specify the configuration directory for the CliFrontend if 
> it is started via the flink shell script. In order to improve the user 
> exprience, I would propose to introduce a {{--configDir}} parameter which the 
> user can use to specify a configuration directory more easily.
