Re: Re: Kafka upgrading help?
OK,thank you for your help. yinghua...@163.com From: Luke Chen Date: 2021-06-15 16:06 To: dev Subject: Re: Kafka upgrading help? Hi, I can see in V2.4.0, we upgraded zookeeper from 3.4.14 to 3.5.5. So, I guess before V2.4.0 is good to go since it's just zookeeper minor version upgrade. But you still need to have a complete test for the upgrade. In your case, I think you can expect the new feature: KRaft mode, to remove zookeeper. FYI ref: https://github.com/apache/kafka/blob/trunk/config/kraft/README.md Thanks.

kafka compiling help?
When I imported the version of Kafka 2.4.1 into the idea, the following error
occurred:
A problem occurred configuring project ':core'.

Because our development environment can't access the external Maven warehouse,
I have changed the following configuration in the file build.gradle to our
internal warehouse address.
repositories {
maven {
url 'http://10.88.100.250:8081/nexus/sdp/content/groups/public/'
}
// mavenCentral()
//jcenter()
}
But when we use it, Kafka project does not connect to the internal Maven
warehouse, it still connects to the external warehouse. Do we need to modify
any configuration?
