Request for a working example of using Pregel API in GraphX using Spark Scala

[Basavaraj]

Hello All

I am a beginner in Spark, trying to use GraphX for an iterative processing by 
connecting to Kafka Stream Processing

Looking for any git reference to real application example, in Scala 

Please revert with any reference to it, or if someone is trying to build, I 
could join them 

Regards
Basavaraj K N
