Kafka performance testing

Hi,

I try to run Kafka performance tests on my hosts. I get this error message:

[User [ at ] Client1 kafka_2.8.0-0.8.0]$ ./bin/kafka-producer-perf-test.sh
Exception in thread "main" java.lang.NoClassDefFoundError: kafka/perf/ProducerPerformance
Caused by: java.lang.ClassNotFoundException: kafka.perf.ProducerPerformance

Could not find the main class: kafka.perf.ProducerPerformance. Program will exit.

The command line generated by the script looks like this:

I unzipped kafka_2.8.0-0.8.0.jar and verified that there is no perf subdirectory.
Kafka deployment package was downloaded this morning from the official Apache mirror.

How this problem can be solved?

Thank you,
