Re: GraphX: Get edges for a vertex

Hi Mas, I never actually worked with GraphX, but one idea: As far as I know, you can directly access the vertex and edge RDDs of your Graph object. Why not simply run a .filter() on the edge RDD to get all edges that originate from or end at your vertex? Regards, Jeff 2015-03-18 10:52 GMT+01:00

Re: GraphX: Get edges for a vertex

Hi, Just to continue with the question. I need to find the edges of one particular vertex. However, (collectNeighbors/collectNeighborIds) provides the neighbors/neighborids for all the vertices of the graph. Any help in this regard will be highly appreciated. Thanks, -- View this message in co

Re: GraphX: Get edges for a vertex

Hi, I think that there are two solutions; 1. Invalid edges send Iterator.empty messages in sendMsg of the Pregel API. These messages make no effect on corresponding vertices. 2. Use GraphOps.(collectNeighbors/collectNeighborIds), not the Pregel API so as to handle active edge lists by yourself.
