      Description

      In order to run compatibility tests with an 0.8.2 producer, and using VerifiableProducer, we use the 0.8.2 kafka-run-tools.sh classpath augmented by the 0.9.0 tools and tools dependencies classpaths.

      Recently, some refactoring efforts moved ThroughputThrottler to org.apache.kafka.common.utils package, but this breaks the existing compatibility tests:

      Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/kafka/common/utils/ThroughputThrottler
              at org.apache.kafka.tools.VerifiableProducer.main(VerifiableProducer.java:334)
      Caused by: java.lang.ClassNotFoundException: org.apache.kafka.common.utils.ThroughputThrottler

              ... 1 more
      

      Given the need to be able to run VerifiableProducer against 0.8.X, I'm not sure VerifiableProducer can depend on org.apache.kafka.common.utils at this point in time.
