kafka replicator connect

[Jalakam Sairam]

Hi... i am trying to run kafka replicator connect stand alone mode and i am getting the following message. Not sure if the process is running or if the messages are getting transferred to another pipeline

I can't say that something is wrong just by looking at this portion of your logs. It seems there are no messages to replicate. 

Couple of suggestions:

1) Increase your log level to DEBUG (or even TRACE) at your connect worker (connect-log4j.properties). It will be more informative. 

2) Double check how you are selecting the topics you want to replicate (properties: topic.whitelist, topic.regex and topic.blacklist) and whether these topics have any records. 

3) Check that these topics have been created on the destination (an even read them to confirm message replication). 

Hope something of the above helps.
