Examples with StreamExecutionEnvironmentFactory org.apache.flink.streaming.api.environment.StreamExecutionEnvironmentFactory used on opensource projects

Example 1 with StreamExecutionEnvironmentFactory

use of org.apache.flink.streaming.api.environment.StreamExecutionEnvironmentFactory in project flink by apache.

the class ScalaShellRemoteStreamEnvironment method disableAllContextAndOtherEnvironments.

public static void disableAllContextAndOtherEnvironments() {
    // we create a context environment that prevents the instantiation of further
    // context environments. at the same time, setting the context environment prevents manual
    // creation of local and remote environments
    StreamExecutionEnvironmentFactory factory = new StreamExecutionEnvironmentFactory() {

        @Override
        public StreamExecutionEnvironment createExecutionEnvironment() {
            throw new UnsupportedOperationException("Execution Environment is already defined" + " for this shell.");
        }
    };
    initializeContextEnvironment(factory);
}
