> Key: FLINK-2761
> URL: https://issues.apache.org/jira/browse/FLINK-2761
> Project: Flink
> Issue Type: Improvement
> Components: Scala Shell
> Affects Versions: 0.10
> Reporter: Stephan Ewen
> Assignee: Sachin Goel
>
> When someone mistakenly creates a new ExecutionEnvironment in the Scala Shell, the programs don't work. The Scala Shell should prevent new ExecutionEnvironment instantiations.
> That can be done by setting a context environment factory that throws an error when attempting to create a new environment.
> See here for a user with that problem:
