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

             Summary: Iterator Data Sink doesn't mention required module
                 Key: FLINK-8285
                 URL: https://issues.apache.org/jira/browse/FLINK-8285
             Project: Flink
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 1.4.0
         Environment: Linux CentOS/7
            Reporter: Julio Biason


In the docs about [https://ci.apache.org/projects/flink/flink-docs-release-1.4/dev/datastream_api.html#iterator-data-sink], it's mentioned that one could use an interator for retrieving the result of the stream.

But there is no mention of any external packages (as it happens with some examples in the metrics) and trying to use causes an error:

[error] object contrib is not a member of package org.apache.flink
[error] import org.apache.flink.contrib.streaming.DataStreamUtils

The line in question (as copied'n'pasted directly from the examples):

import org.apache.flink.contrib.streaming.DataStreamUtils
