> Print usage information for Scala Shell

> Key: FLINK-2613
> URL: https://issues.apache.org/jira/browse/FLINK-2613
> Project: Flink
> Issue Type: Improvement
> Components: Scala Shell
> Affects Versions: 0.10
> Reporter: Maximilian Michels
> Assignee: Nikolaas Steenbergen
> Priority: Minor
> Labels: starter
> Fix For: 0.10
>
>
> The Scala Shell startup script starts a {{FlinkMiniCluster}} by default if
> invoked with no arguments.
> We should add a {{--help}} or {{-h}} option to make it easier for people to
> find out how to configure remote execution. Alternatively, we could print a
> notice on the local startup explaining how to start the shell in remote mode.
