Elasticsearch 服务器启动时出现以下异常

Question

我是 Elasticsearch 和 AWS ec2 的新手，我的 elasticsearch 服务器（部署在 AWS EC2 实例上）开始时出现以下异常：

[2015-01-23 06:36:44,919][ERROR][marvel.agent] [elasticnode] exporter [es_exporter] has thrown an exception:
java.lang.NullPointerException
        at org.elasticsearch.marvel.agent.Utils.extractHostsFromHttpServer(Utils.java:90)

        at org.elasticsearch.marvel.agent.AgentService$ExportingWorker.run(AgentService.java:225)
        at java.lang.Thread.run(Thread.java:745)

我想不出具体原因。请帮助我。

谢谢

Marvel 在完全初始化之前尝试连接到 elasticsearch。您可以安全地忽略该错误，除非它仍然存在。
