我已经下载了Spark 2.1.0和Apache Zeppelin 0.7.0。我已经为Spark,Java和Winutils编辑了我的环境变量(因为我使用的是Windows 10)。我编辑了zeppelin-env.sh和zeppelin-site.xml来导出我的JAVA_HOME和SPARK_HOME。我编辑了zeppelin-site.xml来更改端口号,因为8080已经在使用中。我以管理员身份打开命令行,更改为zeppelin-0.7.0-bin-all目录并运行命令bin \ zeppelin.cmd。我打开浏览器并导航到localhost:8090。 Zeppelin打开,右上角出现绿灯表示我已连接到服务器。一旦我运行"将数据加载到表格中#34;教程我收到一个错误:

日志文件夹中没有可用的日志。一切都在命令行中打印。 %md解释器用作来自"欢迎来到Zeppelin"的代码。我跑完后工作正常。

我已尝试根据issues.apache.org上的ZEPPELIN_305和ZEPPELIN-449更改内存。我试过关掉Windows防火墙。我已经卸载并重新安装,以确保它不是我自己造成的错误,但似乎没有任何工作。

有没有人有相同/类似的问题?任何帮助将非常感激。

您的问题可能在于编辑错误的配置文件。由于您使用的是Windows 10,因此需要编辑zeppelin-env.cmd(而不是用于Linux的zeppelin-env.sh)。请参阅Zeppelin安装指南的link
