-----------------------------------

             Summary: Remove implicit Seq to DataStream conversion
                 Key: FLINK-3413
                 URL: https://issues.apache.org/jira/browse/FLINK-3413
             Project: Flink
          Issue Type: Improvement
          Components: Streaming
    Affects Versions: 0.10.2
            Reporter: Stephan Ewen
            Assignee: Stephan Ewen
             Fix For: 1.0.0


The implicit conversion from {{Seq}} to Flink DataStream needs to create internally a new execution environment.

This method is confusing to use. If one uses the Seq in a program that uses a different execution environment, then different streams run on different execution environments.

The overhead of manually calling {{env.fromElements(seq)}} is quite low.
