Apache Zeppelin 无法启动

分类：编程问答

如何解决Apache Zeppelin 无法启动

这里的新手，请温柔。

有问题的计算机使用 Windows 10 并且 Apache Zeppelin(zeppelin-0.9.0-bin-all.tgz) 拒绝启动。

我尝试从配置文件中删除 .template ，但仍然没有。

它没有通过这一行：INFO [2021-01-29 17:46:29,310] ({main} LuceneSearch.java[]:93) - 使用 C:\Zeppelin\tmp\zeppelin-index 进行存储lucene 搜索索引。

此时不完全确定该怎么做，尝试了此处的解决方案：Apache Zeppelin not loading in a browser in windows 10 和此处：https://gist.github.com/codspire/7b0955b9e67fe73f6118dad9539cbaa2，但我无法弄清楚出了什么问题。

值得注意的是，我单独安装了 Spark (spark-3.0.1-bin-hadoop3.2.tgz)，即使它抛出此警告，它似乎也能工作：21/01/29 18:16:39 WARN ProcfsMetricsGetter : 尝试计算页面大小时出现异常，因此停止报告 ProcessTree 指标

任何建议都将不胜感激，因为我不知道还能尝试什么。

解决方法

我建议你停止在 Windows 下运行 Zeppelin。除了旧版本（如 0.8.0）在自述文件中包含 Windows 之外，新版本的 Zeppelin - 0.9.0 - 在支持的平台列表中甚至没有提到 Windows。

据我了解，Zeppelin 的团队并没有那么大，无法提供 Windows 支持，你会遇到很多 bug，唯一能修复的就是你。

在古代，传递坏消息的信使会被杀死。我希望从那时起有所改变！

您可以尝试在 Docker、WSL2 或带有 Linux 的完整虚拟机中运行 Zeppelin。

在 Windows 中运行 Zeppelin 的最简单方法是安装 Docker for Windows，然后运行类似 docker run -p 8080:8080 --rm --name zeppelin apache/zeppelin:0.9.0
