apache zeppelin已启动但localhost:8080中存在连接错误

Question

在Ubuntu 14上成功构建了apache zepellin之后,我启动了zeppelin并且它说成功启动但是当我去localhost时:8080 Firefox显示无法连接错误,就像它没有启动但是当我从终端检查Zeppelin状态时它表示运行并且我只是复制了配置文件模板,所以配置文件是默认的

更新

将端口更改为8090,这是配置文件,但结果没有变化

以下是zeppelin启动后处于侦听状态的端口

tcp6       0      0 :::8081                 :::*                    LISTEN     
tcp6       0      0 ::1:631                 :::*                    LISTEN     
tcp6       0      0 :::8091                 :::*                    LISTEN     
tcp6       0      0 :::9001                 :::*                    LISTEN     

并且Zeppelin is running [ OK ] 是我运行命令时得到的响应bin/zeppelin-daemon.sh status

Answer 1

检查是否可以到达127.0.0.1:8080。这对我有用，同时localhost:8080也无法实现。

Answer 2

还要检查其他Zeppelin文件,例如interpreter.json笔记本文件.他们可能保存了覆盖您所设置内容的配置值configuration.xsl.

我有一个类似的问题,主要是MASTER设置,但也有端口.我指定了新值,但Zeppelin忽略了它们.我最终发现Zeppelin已经获取了环境变量的值MASTER,并且我不知道,将其保存到interpreter.json文件中.您可以尝试编辑该文件,或重新创建Zeppelin Interpreters.

在我的情况下,我决定不搞乱,只是完全重新安装Zeppelin以确保干净的板条.然后zeppelin-env.sh在开始之前将以下行添加到文件中:

export MASTER=local[*]
export ZEPPELIN_PORT=8088

那很有效.
