【Oozie】ambari安装oozie失败

之前对azkaban的研究比较多，现在开个新坑，对Oozie开始深入了解

Traceback (most recent call last):

resource_management.core.exceptions.ExecutionFailed: Execution of '/usr/bin/yum -d 0 -e 0 -y install extjs' returned 1. Error: Nothing to do

问题原因：/usr/bin/yum -d 0 -e 0 -y install extjs 很明显，在源中不存在extrs,其实在ambari安装的时候，应该就把extjs加入的，但是因为我把这台服务器上的ambari删除了，导致了这个错误

解决方法：

第一种（不支持）：

我们进入其他节点拷贝extjs-2.2-1.noarch.rpm到这台服务器上的指定目录

第二种：

参考https://www.cnblogs.com/julyme/p/5642486.html

通过Ambari把这台服务器上的所有组件都删除,最后删除ambari-agent,重新添加host
