Elasticsearch 用 openJDK11 安装，开放外网访问就报错 UseConcMarkSweepGC 问题

Question

java Version：

[root@localhost ~]# java --version
openjdk 11.0.2 2019-01-15 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.2+7-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+7-LTS, mixed mode, sharing)

把 network.host: localhost 改成 network.host: 104.248.70.201

再重启就提示：

May 30 22:48:28 localhost.localdomain elasticsearch[7022]: OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will like

那应该如何更好的开启外网访问呢？

Answer 1

只是个警告，不是报错
