linux - yum 删除干净卸载 HDP 期间的问题

Question

如 this 等几个链接中所述和 this ，我正在尝试清理卸载 Hortonworks 2.2 数据平台。

在 Linux 中天真，我面临着第一步本身的问题 - 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:

[root@l1031lab ~]# yum remove "HDP*"

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

我有两个问题:

1. 这里的问题是互联网连接吗？
2. 如果是，是否必须要有互联网才能彻底删除所有这些包

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* 匹配的软件包名称。 Yum 包名称区分大小写。根据您想要运行以下的第一个链接:

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

编辑:

更新的命令将导致 yum 扩展包名称以删除任何以该字符串开头的包，因此 bigtop* 将导致 bigtop-jsvc 和 bigtop-tomcat 被删除。添加包的顺序并不重要，因为 yum 足够聪明来处理依赖关系等。
