Its very much possible to use GraphX through Java, though some boilerplate may be needed. Here is an example.
Create a graph from edge and vertex RDD (JavaRDD<Tuple2<Object, Long>> vertices, JavaRDD<Edge<Long>> edges ) <code> ClassTag longTag = scala.reflect.ClassTag$.MODULE$.apply(Long.class); Graph<Long,Float> graph = Graph.apply(vertices.rdd(), edges.rdd(), 0L, StorageLevel.MEMORY_ONLY(), StorageLevel.MEMORY_ONLY(), longTag, longTag); </code> Then basically you can call graph.ops() and do available operations like triangleCounting etc, Best Regards, Sonal Founder, Nube Technologies <http://www.nubetech.co> Reifier at Strata Hadoop World <https://www.youtube.com/watch?v=eD3LkpPQIgM> Reifier at Spark Summit 2015 <https://spark-summit.org/2015/events/real-time-fuzzy-matching-with-spark-and-elastic-search/> <http://in.linkedin.com/in/sonalgoyal> On Tue, May 31, 2016 at 11:40 AM, Santoshakhilesh < santosh.akhil...@huawei.com> wrote: > Hi , > > Scala has similar package structure as java and finally it runs on JVM so > probably you get an impression that its in Java. > > As far as I know there are no Java API for GraphX.
