I think this is good to merge.
In general, relying on static variables to cache things is a bit of a
fragile mechanism. Maybe we can improve that when bringing the Batch and Stream
environment together.
For now, should be good, though.
> Add implicit conversion from scala streams to DataStreams
> ---------------------------------------------------------
>
> Key: FLINK-1344
> URL: https://issues.apache.org/jira/browse/FLINK-1344
> Project: Flink
> Issue Type: New Feature
> Components: Streaming
> Reporter: Paris Carbone
> Assignee: Paris Carbone
> Priority: Trivial
>
> Source definitions in the scala-api work either with a collector in a UDF, or
> by passing a Seq that could also be a lazily generated scala Stream. To
> encourage a purely functional coding style in the streaming scala-api while
> also adding some interoperability with scala constructs (ie. Streams, Lists)
> it would be nice to add an implicit conversion from Seq[T] to DataStream[T].
> [EDIT] The StreamExecutionEnvironment should be statically initialised to
> allow for an implicit source definition
> (An upcoming idea would be for sinks to also support wrapping up flink
> streams to scala streams for full interoperability with scala streaming code.)
