Zeppelin断开状态错误

Question

我正在使用Zeppelin 0.70。我可以从git源构建zeppelin。当我尝试使用下面的命令在该端口8000上启动zeppelin时，它运行良好。

./ zeppelin-daemon start

但是在端口9000上使用grunt serve命令后它无法正常工作，但它启动良好并且显示Web套接字断开连接错误。

[root@sandbox zeppelin-web]# ./grunt serve

    Done, without errors.

我登录了控制台;

XMLHttpRequest cannot load http://localhost:8080/api/security/ticket. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9000' is therefore not allowed access. The response had HTTP status code 404.

我将8080更改为8000。

请告诉我如何解决此问题。

我认为grunt已在0.7版本中替换为npm，您是否可以尝试npm run dev命令？

更新：ZEPPELIN-2154下与此相关的问题。为了在您的案例中修复它，您可以删除if statement here中的3行，并在源代码中将其替换为port = 8000;。它可能是临时修复，直到补丁被提交以使其可配置。
