CDH卸载

香蕉与打火机2014年12月12日小云云

边翻译边干：http://www.cloudera.com/content/cloudera/en/documentation/cloudera-manager/v5-0-0/Cloudera-Manager-Installation-Guide/cm5ig_uninstall_cm.html

配置情况

一台cm server（使用mysql）

四台cdh主机

默认的用户目录

以下目录是默认安装时的各个工具的目录：

/var/lib/flume-ng /var/lib/hadoop* /var/lib/hue /var/lib/navigator /var/lib/oozie /var/lib/solr /var/lib/sqoop* /var/lib/zookeeper/dfs /mapred /yarn

假如在安装时自己改过，那就在重新安装的时候注意删除自定义的目录。

停止各种cdh及cm的服务

可以在界面上操作

删除cm server上的服务及安装

检查cm server状态

 删除cdh中的组件

删除cloudera manager的数据

Shell

[root@hdp02 ~]# rm -Rf /usr/share/cmf /var/lib/cloudera* /var/cache/yum/cloudera* /var/log/cloudera* /var/run/cloudera*rm: cannot remove `/var/run/cloudera-scm-agent/process': Device or resource busy

[root@hdp02~]# rm -Rf /usr/share/cmf /var/lib/cloudera* /var/cache/yum/cloudera* /var/log/cloudera* /var/run/cloudera*

rm:cannot remove`/var/run/cloudera-scm-agent/process':Device orresource busy

重启后试试 物理机重启那叫一个慢。。。。。。。。

重启以后删掉了。

删除cloudera manager的lock文件

Shell

[root@hdp04 ~]# rm /tmp/.scm_prepare_node.lockrm: cannot remove `/tmp/.scm_prepare_node.lock': No such file or directory

1

2

[root@hdp04~]#  rm /tmp/.scm_prepare_node.lock

rm:cannot remove`/tmp/.scm_prepare_node.lock':No such fileor directory

竟然没有，可能是因为通过命令正常关闭的，本身没有产生lock。

再删除其他hadoop的组件

Shell

[root@hdp04 ~]# rm -Rf /var/lib/flume-ng /var/lib/hadoop* /var/lib/hue /var/lib/navigator /var/lib/oozie /var/lib/solr /var/lib/sqoop* /var/lib/zookeeper[root@hdp04 ~]#

[root@hdp04~]#

Shell

rm -Rf /dfs /mapred /yarn

1

rm-Rf/dfs/mapred/yarn

*我没有删除/dfs，因为最初物理分区直接给分了个/dfs出来。
