Trouble ingesting data from kafka to druid without using storm

Can somebody help me with using tranquility for data ingestion from kafka to druid without using storm in a very basic setup?
I’ve these four nodes up : coordinator, broker, historical and overlord.

Also i have Tranquility kafka application running using this :

bin/tranquility kafka -configFile conf/tranquility-kafka.json.

Now when i insert data in a kafka topic mentioned in tranquility-kafka.json, i’m getting the error :
