Zeppelin：配置错误

Question

我在尝试运行 zeppelin 时收到此错误消息：

OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=512m; support was removed in 8.0
 WARN [2020-05-25 09:08:31,181] ({main} ZeppelinConfiguration.java[create]:159) - Failed to load configuration, proceeding with a default

    at org.apache.zeppelin.server.ZeppelinServer.main(ZeppelinServer.java:129)

我正在部署 zeppelin，没有任何配置。

编辑：

设置ZEPPELIN_PORT后的附加错误消息：

看起来您正在使用links with Docker compose 或类似的东西，因此它为Zeppelin 容器定义了ZEPPELIN_PORT 环境变量，其形式为tcp://172.30.239.172:80。但是这个环境变量应该只包含端口，比如80，或者8080。

要解决此问题，请尝试将链接容器从 zeppelin 重命名为其他名称，这样它就不会覆盖 Zeppelin 本身使用的环境变量。
