Spark streaming on AWS EC2 error . Please help

I am running Spark streaming on AWS EC2 in standalone mode.

When I do a spark-submit, I get the following message. I am subscribing to
3 kafka topics and it is reading and processing just 2 topics. Works fine
in local mode.
Appreciate your help. Thanks
