Vasia Kalavri commented on FLINK-4204:
--------------------------------------

Separating drivers and examples sounds like a good idea. Do you think we should 
add drivers for every library algorithm? Isn't it enough to provide 1-2 
examples and have good documentation about how users can write their own 
drivers?

>          Issue Type: Improvement

> The gelly-examples has grown quite big (14 examples) and contains several 
> examples that illustrate the same functionality. Examples should help users 
> understand how to use the API and ideally show how to use 1-2 features.
> Also, it is helpful to state the purpose of each example in the comments.
> We should keep the example set small and move everything that does not fit 
> there to the library.
> I propose to remove the following:
> - ClusteringCoefficient: the functionality already exists as a library method.
> - HITS: the functionality already exists as a library method.
> - JaccardIndex: the functionality already exists as a library method.
> - SingleSourceShortestPaths: the example shows how to use scatter-gather 
> iterations. HITSAlgorithm shows the same feature plus the use of aggregators. 
> I propose we keep this one instead.
> - TriangleListing: the functionality already exists as a library method
