如何解决通过 Brew 升级 Eleastic Search - 现在不会以无法识别的 VM 选项“UseConcMarkSweepGC”错误开始
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.

我尝试重新安装并链接 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
解决方法
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
评论这些，现在一切都很好?
