Kafka无法识别的VM选项'PrintGCDateStamps' [英] Kafka Unrecognized VM option 'PrintGCDateStamps'

问题描述

我在远程服务器上安装了Kafka，并且尝试运行时

I installed Kafka on a remote server, and when I tried to run

~/kafka/bin/zookeeper-server-start.sh ~/kafka/config/zookeeper.properties

我收到一个错误

Unrecognized VM option 'PrintGCDateStamps'

kafka服务器无法启动.这不是在vm中运行，而是在已正确安装Java的Ubuntu Server 16.04上直接运行.有什么办法可以简单地纠正吗?

And the kafka server failed to start. This was not being run in a vm, and was being run directly on Ubuntu Server 16.04 with Java properly installed. Any way this can be corrected simply?

推荐答案

实际上，Kafka可以与Java的较新版本配合使用.我遇到了同样的问题，并且在kafka/bin/kafka-run-class.sh脚本中发现了一个错误，在该脚本中Java版本被错误地解析.

Actually, Kafka works fine with newer versions of Java. I had the same problem, and found an error in the kafka/bin/kafka-run-class.sh script, where the Java version was incorrectly parsed.

此行捕获了太多的版本字符串:

This line grabs too much of the version string:

JAVA_MAJOR_VERSION=$($JAVA -version 2>&1 | sed -E -n 's/.* version "([^.-]*).*"/\1/p')

这使if [[ "$JAVA_MAJOR_VERSION" -ge "9" ]]条件无法识别正确的Java版本，并添加了一些不受支持的GC选项.

This makes the if [[ "$JAVA_MAJOR_VERSION" -ge "9" ]] condition fail to identify the correct Java version, and adds some unsupported GC options.

将上面的行更改为此可以解决我的问题:

Changing the line above to this solved my problem:

JAVA_MAJOR_VERSION=$($JAVA -version 2>&1 | sed -E -n 's/.* version "([^.-]*).*/\1/p')
