Ji Dai updated SPARK-20454:
---------------------------
Target Version/s: (was: 2.1.0)
> Improvement of ShortestPaths in Spark GraphX
> --------------------------------------------
>
> Key: SPARK-20454
> URL: https://issues.apache.org/jira/browse/SPARK-20454
> Project: Spark
> Issue Type: Improvement
> Components: GraphX, MLlib
> Affects Versions: 2.1.0
> Reporter: Ji Dai
> Labels: patch
>
> The output of ShortestPaths is not enough. ShortestPaths in Graph/lib is
> currently in a simple version and can only return the distance to the source
> vertex. However, the shortest path with intermediate nodes on the path is
> needed and if two or more paths holds the same shortest distance from source
> to destination, all these paths need to be returned. In this way,
> ShortestPaths will be more functional and useful.
> I think I have resolved the concern above with a improved version of
> ShortestPaths which also based on the "pregel" function in GraphOps.
> Can I get my code reviewed and merged?
