-----------------------------------
Summary: Prevent instantiation of new ExecutionEnvironments in the
Scala Shell
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
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.
