Apache drill on ec2 集群连接超时

Question

我正在尝试在由 ec2 实例组成的 3 节点集群上进行钻取运行。我配置了 drill-override.conf 文件，以便它可以连接到我的 zookeeper 集群。然后开始 drillbit.sh 在所有三个节点上，检查状态，它们是运行。我试着开钻使用 drill-conf 并且第一次工作时我确保它可以看到所有三个钻头通过使用：

    SELECT * FROM sys.drillbits;

它正确显示了所有三个钻头。但是，我重新启动集群并尝试重试处理这是我得到的错误：

[ec2-user@ip-<private IP> bin]$ ./drill-conf

我在几个地方查过这个并尝试了他们的解决方案，其中之一是确保 /etc/hosts 配置正确，但未能解决问题。还有什么我可以尝试解决的问题？

Answer 1

找到解决方案：

必须通过让正确的流量进入端口 31010 来确保我的 ec2 instaqnces 安全组配置正确。
