CDH实操--集群卸载 
502
0systemctl stop cloudera-scm-agent #所有节点执行
systemctl stop cloudera-scm-server #cdh01节点执行rm -rf /opt/cloudera/usr/share/cmf/uninstall-cloudera-manager.sh注：若集群中未安装uninstall-cloudera-manager.sh，则使用下面命令进行卸载
yum remove cloudera-manager-server yyum remove cloudera-manager-* y运行下面清楚命令：
yum clean allrm -rf /dfs /usr/share/cmf /var/lib/cloudera* /var/cache/yum/x86_64/var/run/cloudera* /var/log/cloudera-scm-*
卸载mouont目录(一次卸载不了可以多试两次)
umount /run/cloudera-scm-agent/process
rm -rf /run/cloudera-scm-agentps -ef | grep 'hadoop' | grep -v 'grep'| awk '{print \$2}'

最好把/tmp目录下的所有有关cloudera manager的临时文件删除
rm -rf /tmp/cmf* /tmp/scm*DROP DATABASE amon;
DROP DATABASE hue;
DROP DATABASE nav;
DROP DATABASE navms;

DROP DATABASE rman;
