maven下载包失败，手动下载塞到maven依赖库中
安装zeppelin，官方有编译好的二进制安装文件，但是编译好的文件里面好多包的版本跟我自己环境下的平台版本不一样，因此不得不手工下载源码，选择合适版本编译。
maven编译需要根据pom文件中的依赖库，来下载很多包，往往遇到连接超时的问题。下面遇到的是yarn-v0.18.1.tar.gz这个包下载不了，重新编译了好几次，还是不行。

前面编译都成功了，在zeppelin-web这部失败了，还好，maven可以继续编译。在之前执行的命令后面跟上这个：-rf :zeppelin-web

再次运行时会告诉你包会从哪下载到哪。。然后根据这个提示去下载地址手动下载，放到该位置。
再次继续zeppelin-web的编译即可。。。。
