【问题描述】：

正在对 ES 进行故障排除，并认为我会尝试升级到 7.10.2：

Dans-MacBook-Pro:~ aximus$ brew services restart elasticsearch
Stopping `elasticsearch`... (might take a while)
==> Successfully stopped `elasticsearch` (label: homebrew.mxcl.elasticsearch)
==> Successfully started `elasticsearch` (label: homebrew.mxcl.elasticsearch)

启动失败：

Dans-MacBook-Pro:~ aximus$ tail -f /usr/local/var/log/elasticsearch.log

    error:
    Unrecognized VM option 'UseConcMarkSweepGC'
    Error: Could not create the Java Virtual Machine.
    Error: A fatal exception has occurred. Program will exit.

        at org.elasticsearch.tools.launchers.JvmOptionsParser.main(JvmOptionsParser.java:95)

我尝试重新安装和链接 openjdk@11 (11.0.10)，但没有成功。目前死在水中：

Dans-MacBook-Pro:~ aximus$ curl 127.0.0.1:9200
curl: (7) Failed to connect to 127.0.0.1 port 9200: Connection refused

【解决方案1】：

偶然发现一个相关问题并意识到这是在我的/usr/local/etc/elasticsearch/jvm.options 文件中：

## GC configuration
#-XX:+UseConcMarkSweepGC
#-XX:CMSInitiatingOccupancyFraction=75
#-XX:+UseCMSInitiatingOccupancyOnly

评论了这些，现在一切都很好?
