Ji Dai updated SPARK-20454:
---------------------------
Description:
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?
