--------------------------------------------------------------
I agree with [~twalthr] at this point. It would be better adding more comments
on those method like those method can not support consistency guarantees
instead of deprecating them. Like in data analysis for data cleaning, we do
need strong consistency guarantees and many data are drop and duplicate.

> Project: Flink
> Issue Type: Improvement
> Components: DataStream API
> Reporter: Aljoscha Krettek
> Assignee: Aljoscha Krettek
> Priority: Major
> Fix For: 1.5.0
>
>
> Some output methods on {{DataStream}} that write text to files are not safe
> to use in a streaming program as they have no consistency guarantees. They
> are:
> - {{writeAsText()}}
> - {{writeAsCsv()}}
> - {{writeToSocket()}}
> - {{writeUsingOutputFormat()}}
> Along with those we should also deprecate the {{SinkFunctions}} that they use.
