Subject Adjacency List representation in Spark
Date Wed, 17 Sep 2014 13:43:22 GMT

We are building an adjacency list to represent a graph. Vertexes, Edges and
Weights for the same has been extracted from hdfs files by a Spark job.
Further we expect size of the adjacency list(Hash Map) could grow over
How can we represent this in RDD, so that it will distributed in nature?

Basically we are trying to fit HashMap(Adjacency List) into Spark RDD. Is
there any other way other than GraphX?

Thanks and Regards,
