Question

我正在使用fabric8 kubernetes插件进行elasticsearch 2.1集群发现。在启动期间，由于以下错误，我的ES失败：

[2015-12-15 00:30:28,049][WARN ][io.fabric8.elasticsearch.discovery.kubernetes.KubernetesUnicastHostsProvider] [Freakmaster] Exception caught during discovery: access denied ("java.io.FilePermission" "/home/elasticsearch/.kube/config" "read")

正如您所看到的，由于某种原因，配置假定/ home / elasticsearch为安装位置。我的ES实际上是在/ opt / elasticsearch设置的。我甚至通过了path.home配置参数并设置了HOME env var。但错误仍然存在。

非常感谢任何帮助/建议。

您需要在禁用安全管理器的情况下运行 - 有关设置，请参阅https://github.com/fabric8io/elasticsearch-cloud-kubernetes/blob/master/elasticsearch.yml#L20。我已将此添加到自述文件中。

插件只能从2.2更新安全策略 - 有关详细信息，请参阅https://github.com/elastic/elasticsearch/issues/14880。
