问题
I was trying to run Performance test as per the following article for Apache Kafka
Reference:
https://engineering.linkedin.com/kafka/benchmarking-apache-kafka-2-million-writes-second-three-cheap-machines
Linked-in tests: https://gist.github.com/jkreps/c7ddb4041ef62a900e6c
But when I run this:
bin/kafka-run-class.sh org.apache.kafka.clients.tools.ProducerPerformance test7 50000000 100 -1 acks=1 bootstrap.servers=localhost:9092 buffer.memory=67108864 batch.size=8196
It shows the error:
Error: Could not find or load main class org.apache.kafka.clients.tools.ProducerPerformance
Is it about kafka version? Or I need to download the class from somewhere else?
Where is my org.apache.kafka.clients.tools.ProducerPerformance class? Please suggest..
回答1:
Package name of ProducerPerformance
has been changed from
org.apache.kafka.clients.tools
to org.apache.kafka.tools
.
For more details, check my answer for a possible duplicate question.

I think you need to build the project first before running this command .. you can use build tool such as sbt
as documented in their official web site
