Zeppelin是一个Web笔记形式的交互式数据查询分析工具,可以在线用scala和SQL对数据进行查询分析并生成报表。Zeppelin的后台数据引擎可以是Spark(目前只有Spark),开发者可以通过实现更多的解释器来为Zeppelin添加数据引擎。

本文,介绍zeppelin 编译安装,入门使用介绍。

Requirements

  • Git
  • Java 1.7
  • Tested on Mac OSX, Ubuntu 14.X, CentOS 6.X, Windows 7 Pro SP1
  • Maven (if you want to build from the source code)
  • Node.js Package Manager (npm, downloaded by Maven during build phase)

[root@gitlab-machine zeppelin-web]# grunt build
ERROR [launcher]: No binary for PhantomJS browser on your platform.

1. 初步查看日志,可以看到是由于上一个错误的库phantomjs引起的错误。
2. 进一步查看日志如下,发现在执行npm install可以通过了,而执行“bower --allow-root install”开始报错。

最终修改pom.xml信息解决问题,网上这么说的,编译过后启动web页面首页显示有些许问题,无奈啊,前端太渣,这个项目用到了grunt,bower,node,npm等前端技术,这个web模块比较难通过,tez-ui也一样,相对来说编译都不那么顺利。

Address already in use

需要注意的是,Zeppelin默认是在8080端口上启动相关的web服务的,在你服务器上,如果这个端口已经被占用了,那么会导致Zeppelin启动失败,并在日志里面抛出以下的异常;ps:我的这个报错就因为我在主机上部署了gitlab导致端口被占用:
