I am not using confluent, I am able to run the Zookeeper and Kafka successfully. And following the steps to Mongo-kafka connect using jar file and am getting an error. Once I download the mongo-kafka-connect-0.2-all.jar file from maven tech do I need to register? I have updated the plugin path correctly. can someone help me, please?

You have an error because Kafka Connect has not loaded the connector JAR that you're trying to use : 

Failed to find any class that implements Connector and which name matches com.mongodb.kafka.connect.MongoSinkConnector

One option you have is to use the Confluent Hub tool to install the connector - you can you use it without running Confluent Platform IIRC: 

confluent-hub install mongodb/kafka-connect-mongodb:0.2

The Confluent Hub tool handles stuff like plugin.path automagically so that you don't have to.

Alternatively, you can configure it yourself. Make sure plugin.path for your Kafka Connect worker(s) is set to include the folder in which you have the MongoDB sink connector JAR.
