Resolution: Fixed
> Add collect() operation on DataStream
> -------------------------------------
>
> Key: FLINK-19508
> URL: https://issues.apache.org/jira/browse/FLINK-19508
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Reporter: Aljoscha Krettek
> Assignee: Seth Wiesman
> Priority: Major
> Labels: pull-request-available
>
> With the recent changes/additions to {{DataStreamUtils.collect()}} that make
> it more robust by using the regular REST client to fetch results from
> operators it might make sense to add a {{collect()}} operation right on
> {{DataStream}}.
> This operation is still not meant for big data volumes but I think it can be
> useful for debugging and fetching small amounts of messages to the client.
> When we do this, we can also think about changing {{print()}} to print on the
> client instead of to the {{TaskManager}} stdout. I think the current
> behaviour of this operation is mostly confusing for users.
