    A few things cause this exception: 1) Check if you have all jars and if they're in the correct path when running. 2) Your classpath might be broken, you can define it in the command line with "java -cp yourClassPath" or at your IDE if you're using one.
  4. Speed up your debug routine!

    This was caused by a failure to instantiate Kafka broker. Check your dependencies.
