> Add configDir parameter to CliFrontend and flink shell script
> -------------------------------------------------------------
>
> Key: FLINK-4084
> URL: https://issues.apache.org/jira/browse/FLINK-4084
> 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.
