ingestion error + Path length must be > 0 #2

Hi I am using Kafka 8 to run this hybrid example. I get this exceptions when I try to run (It says the error is because it expects the path length to be > 0 and is found to be 0). Any idea on how to fix this?

@kandu009 - I'm getting the same. Were you able to resolve this?

https://github.com/upio/summingbird-hybrid-example works for me

@dkwestbr yeah upio example works. The above error gets fixed with java 1.7 version.
