Does "Tutorial: Load from Kafka" miss information?

Hi all,

I followed the tutorial link http://druid.io/docs/latest/tutorials/tutorial-kafka.html to install/config kafka after had done Druid quickstart (http://druid.io/docs/latest/tutorials/quickstart.html) with both druid and tranquility installed and running.
However I can not see data in druid after they has been inserted into kafka like the tutorial said. Am I missing anything?

Thanks,

Jimmy

Another question is: how to enable the logging for tranqility server? From there I may be able to debug why the messages in kafka’s ‘metrics’ topic weren’t consumed by tranqility and produce into druid.

Thanks,

Jimmy

Nobody really knows the answer?
