kafka-connect分布式模式

Question

I am trying to start kafka-connect using:

connect-distributed /etc/schema-registry/connect-avro-distributed.properties

, but then I get:

[2017-02-15 12:45:35,962] INFO Instantiated task mysql-adventureworks-source-0 with version 3.1.2 of type io.confluent.connect.jdbc.source.JdbcSourceTask (org.apache.kafka.connect.runtime.Worker:264)

The schema url is presented. I've also tried to start it using:

connect-distributed /etc/kafka/connect-distributed.properties

, which uses the json format, but I get the same error.

Any ideas ?

Please start Schema registry service pointing to the right property file. It should work.
