1. 关闭集群中的所有服务。
这个可以通过clouder manger 主页关闭集群。
2. 卸载
[root@master ~]# /usr/share/cmf/uninstall-cloudera-manager.sh
注意:如果集群中没有安装uninstall-cloudera-manager.sh,使用下面的命令卸载:
a、停止Cloudera Manager Server及其数据库
a、停止Cloudera Manager Server及其数据库
b、卸载Cloudera Manager Server及其数据库
sudo yum remove cloudera-manager-server
sudo yum remove cloudera-manager-server-db
[root@slave1 ~]# service cloudera-scm-agent stop
[root@slave1 ~]# service cloudera-scm-agent stop
一下都是所有要卸载的集群均要执行清除工作:
[root@master ~]# umount /var/run/cloudera-scm-agent/process
[root@slave1 ~]# umount /var/run/cloudera-scm-agent/process
[root@slave2 ~]# umount /var/run/cloudera-scm-agent/process
[root@master ~]# rm -rf /usr/share/cmf /var/lib/cloudera* /var/cache/yum/x86_64/6/cloudera* /var/log/cloudera* /var/run/cloudera* /etc/cloudera*
3. 卸载安装包:
[root@slave1 ~]# rpm -qa | grep cloudera
[root@slave2 ~]# for f in `rpm -qa | grep cloudera ` ; do rpm -e ${f} ; done (如果有保存,在执行一遍)
4. 清除安装文件
rm -rf /var/lib/hadoop-* /var/lib/impala /var/lib/solr /var/lib/zookeeper /var/lib/hue /var/lib/oozie /var/lib/pgsql /var/lib/sqoop2 /data/dfs/ /data/impala/ /data/yarn/ /dfs/ /impala/ /yarn/ /var/run/hadoop-*/ /var/run/hdfs-*/ /usr/bin/hadoop* /usr/bin/zookeeper* /usr/bin/hbase* /usr/bin/hive* /usr/bin/hdfs /usr/bin/mapred /usr/bin/yarn /usr/bin/sqoop* /usr/bin/oozie /etc/hadoop* /etc/zookeeper* /etc/hive* /etc/hue /etc/impala /etc/sqoop* /etc/oozie /etc/hbase* /etc/hcatalog
//只删除hadoop系列的,不要删除其他软件的,否则其他软件的版本控制会被破坏
[root@master alternatives]# rm -rf ` find /var/lib/alternatives/* ! -name "mta" ! -name "print" ! -name "zlibrary-ui" -mtime -3`
[root@master alternatives]# rm -rf /etc/alternatives/*
5. 杀死相关进程:
for u in hdfs mapred cloudera-scm hbase hue zookeeper oozie hive impala flume; do sudo kill $(ps -u $u -o pid=); done
6. 删除parcel包分发文件和解压文件
rm -rf /opt/cloudera/parcel-cache /opt/cloudera/parcels
到此卸载完毕。
