I don't think it will work. Spark needs input (to read graph data) and output (to write graph data).  JanusGraph currently only provides Hadoop InputFormat based reading from JanusGraph for OLAP.

In Tinkerpop, there are InputRDD and OutputRDD interfaces, which are by Spark (SpackGraphComputer).  (Search for Tinkerpop InputRDD.)

Unfortunately, JanusGraph provides no implementations other than the InputFormat based at the moment.

Thanks,

Jerry

Hi All,

   I am pretty new to Janusgraph and want to get some suggestions from you. Previously I posted a question about using ES as backend storage, and got some good feedback from Jason (Thanks!).  Now here comes another question: If I want to use janusgraph spark standalone without Hadoop for OLAP,  can some one point me a direction? Basically I have spark standalone deployed on kubernetes, how could that be used for OLAP? 

Thanks a lot!

Wei
