[jira] [Commented] (KAFKA-2807) Movement of throughput throttler to
common broke upgrade tests
[ https://issues.apache.org/jira/browse/KAFKA-2807?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15000934#comment-15000934 ]
Ewen Cheslack-Postava commented on KAFKA-2807:
----------------------------------------------
[~geoffra] Hmm, I moved it into common because that seemed the logical place given it was now to be used by both tools and copycat-tools classes. I think we could probably resolve this by moving it back to tools and have copycat-tools depend on tools. It's a little awkward, but I don't think would cause any problems for copycat-tools.

> Key: KAFKA-2807
> URL: https://issues.apache.org/jira/browse/KAFKA-2807
> Project: Kafka
> Issue Type: Bug
> Reporter: Geoff Anderson
> Assignee: Geoff Anderson
> Fix For: 0.9.0.0

>
> 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:

> 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.
