Hi Robin, I am using Spark 1.3 and I am not able to find the api Graph.fromEdgeTuples(edge RDD, 1)
Regards, Praveen Well you can use a similar tech to generate an RDD[(Long, Long)] (that’s what the edges variable is) and then create the Graph using Graph.fromEdgeTuples. ------------------------------------------------------------------------------- Robin East *Spark GraphX in Action* Michael Malak and Robin East Manning Publications Co. http://www.manning.com/books/spark-graphx-in-action On 11 Jan 2016, at 12:30, praveen S <mylogi...@gmail.com> wrote: Yes I was looking something of that sort.. Thank you. Actually I was looking for a way to connect nodes based on the property of the nodes.. I have a set of nodes and I know the condition on which I can create an edge..
