Elasticsearch启动出现 node validation exception

Elasticsearch启动出现 node validation exception 启动失败。异常如下

1.system call filters failed to install
2.system call filters failed to install; check the logs and fix your configuration or disable system call filters at your own risk

解决

在elasticsearch.yml添加如下配置：
