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，当我尝试运行时

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'

并且kafka服务器启动失败.这不是在虚拟机中运行，而是直接在正确安装 Java 的 Ubuntu Server 16.04 上运行.有什么办法可以简单地纠正这个问题?

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 与较新版本的 Java 一起工作得很好.我也遇到了同样的问题，在kafka/bin/kafka-run-class.sh脚本中发现错误，Java版本解析错误.

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.

这一行抓取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')

这使得 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解决了我的问题:

Changing the line above to this solved my problem:

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