Question

如this和this等几个链接所述，我正在尝试清理未安装的Hortonworks 2.2数据平台。

在Linux中天真，我从第一步本身就面临问题 - 删除已安装的HDP包。

[root@l1031lab ~]# yum list installed | grep HDP

我试图一次性删除所有这些包：

No package HDP* available.
  * Maybe you meant: hdp-select, hdparm
No Packages marked for removal

我有两个问题：

互联网连接是否存在问题？
如果是，则必须使用Internet来清除所有这些软件包

Answer 1

您的互联网连接不是问题。问题是yum无法找到与要删除的HDP*匹配的包名称。百胜包名称区分大小写。根据您想要运行以下内容的第一个链接：

sudo yum remove bigtop* hbase* zookeeper* hadoop* hdp-* phoenix*

编辑：

更新的命令将导致yum扩展程序包名称以删除以字符串开头的任何程序包，因此bigtop*将导致bigtop-jsvc和bigtop-tomcat被删除。添加包的顺序无关紧要，因为yum足够聪明，可以处理依赖项等。

Answer 2

你去吧！这是您的问题的解决方案。我挣扎了好几个星期，尝试一遍又一遍地卸载和重新安装，最后决定在这里分享：How to completely remove and uninstall hadoop componens

诀窍是基本上删除指向HDP组件所在位置的所有符号链接，因为这是造成80％问题的原因。

yum在清除卸载HDP期间删除问题
