Kafka 错误：无法找到或加载主类 .home.kafka.kafka.config.server.properties

Question

I followed the instructions here , but when I try to start Kafka with this command I get an error:

kafka@vertica-2:~$ ~/kafka/bin/kafka-server-start.sh ~/kafka/config/server.properties

Error: Could not find or load main class .home.kafka.kafka.config.server.properties

Answer 1

Make sure you downloaded the bin version, not the uncompiled source(unless you compile it yourself). This error will happen when trying to start the server from uncompiled source.

Answer 2

Update your Java version to be compatible with particular Kafka build. You can use below link to update your Java version:
