卸载CDH5.14.2

1.在Cloudera Manager控制台停止所有服务&＃xff1a;

2. 停止Cloudera Manager service

3. 移除parcel包

假如是通过 packages 来安装的&＃xff0c;那么请跳过这个步骤。本文是针对parcel包方式进行安装。
在CM界面右上角点击Parcel包的图标&＃xff1a;

在页面右边点击停用CDH5&＃xff0c;”停用”对于英文(Deactive)

4.停止Server和Client服务

rpm包安装方式执行以下命令&＃xff1a;

在master节点执行以下命令&＃xff1a;

systemctl stop cloudera-scm-agent
systemctl stop cloudera-scm-server

在每个slave节点执行以下命令&＃xff1a;

systemctl stop cloudera-scm-agent

完全离线方式安装执行&＃xff08;执行过程同上&＃xff09;&＃xff1a;

/opt/cm-5.14.2/etc/init.d/cloudera-scm-server stop
/opt/cm-5.14.2/etc/init.d/cloudera-scm-agent stop

5. 暴力杀进程&＃xff08;每个节点都需要执行&＃xff09;

ps -ef | grep cloudera | grep -v grep | cut -b10-15 | xargs kill -9
ps -ef | grep supervisord | grep -v grep | cut -b10-15 | xargs kill -9

6. 卸载/var/run/cloudera-scm-agent/process

rpm包安装方式执行
在master节点执行&＃xff1a;

umount /var/run/cloudera-scm-agent/process
umount /var/run/cloudera-scm-server/process

在每个slave节点执行&＃xff1a;

umount /var/run/cloudera-scm-agent/process

完全离线安装执行&＃xff08;执行步骤同上&＃xff09;

umount /opt/cm-5.14.2/run/cloudera-scm-agent/process
umount /opt/cm-5.14.2/run/cloudera-scm-server/process

7. 卸载安装包&＃xff08;每个节点执行&＃xff09;

rpm包安装的执行&＃xff1a;

rpm -qa | grep cloudera | xargs rpm -e --nodeps

完全离线安装的则跳过此步骤

8. 在每个节点删除相应文件夹和数据目录

删除Cloudera Manager数据 、数据库存放路径、Cloudera Manager Lock 文件、用户数据、清除安装文件 &＃xff08;安装方式不一样&＃xff0c;可能配置文件路径不一样&＃xff0c;删除时候注意&＃xff0c;小心删错别的文件&＃xff0c;安装的服务不一样&＃xff0c;可能涉及到的文件路径有差别&＃xff0c;以下是默认路径&＃xff09;&＃xff0c;将以下语句保存到removeALL.sh脚本里并分发到各个节点执行&＃xff1a;

for i in {7..10};
dossh 10.10.1.$i "rm -rf /usr/share/cmf /var/lib/cloudera* /var/cache/yum/cloudera* /var/log/cloudera* /var/run/cloudera* /etc/alternatives/yarn*; rm -rf /var/lib/cloudera-scm-server-db /etc/alternatives/sentry* /etc/alternatives/solr*; rm -rf /tmp/.scm_prepare_node.lock /tmp/hsperfdata_hadoop /tmp/hsperfdata_hdfs /tmp/hsperfdata_mapred /tmp/hsperfdata_zookeeper /tmp/hsperfdata_cloudera-scm /tmp/hadoop-root; 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; rm -rf /dfs /mapred /yarn /etc/alternatives/avro* /etc/alternatives/beeline*; rm -rf /etc/cloudera* /etc/alternatives/bigtop* /etc/alternatives/catalogd* /etc/alternatives/cli_* /etc/alternatives/hue* /etc/alternatives/sqoop*; rm -rf /var/cache/yum/x86_64/7/cloudera* /etc/alternatives/llama* /etc/alternatives/*spark* /etc/alternatives/pig* /etc/alternatives/mahout*; rm -rf /var/lib/hadoop-* /var/lib/impala /var/lib/solr /var/lib/zookeeper /var/lib/hue /var/lib/oozie /var/lib/pgsql /etc/alternatives/impala*; rm -rf /var/lib/sqoop2 /data/dfs/ /data/impala/ /data/yarn/ /dfs/ /impala/ /yarn/ /etc/alternatives/oozie* /etc/alternatives/mapred* /etc/alternatives/mahout*; rm -rf /var/run/hadoop-*/ /var/run/hdfs-*/ /usr/bin/hadoop* /usr/bin/zookeeper* /usr/bin/hbase* /etc/alterniatives/hadoop* /etc/alternatives/hbase*; rm -rf /usr/bin/hive* /usr/bin/hdfs /usr/bin/mapred /usr/bin/yarn /usr/bin/sqoop* /usr/bin/oozie /etc/alternatives/hcat* /etc/alternatives/hdfs*; rm -rf /etc/hadoop* /etc/zookeeper* /etc/hive* /etc/hue /etc/impala /etc/sqoop* /etc/oozie /etc/hbase* /etc/hcatalog /etc/alternatives/hive*; rm -rf /var/run/zookeeper /etc/alternatives/flume* /etc/alternatives/zookeeper* /etc/alternatives/parquet* /etc/alternatives/whirr; rm -rf /tmp/scm_prepare_node* /tmp/.scm_prepare_node.lock /etc/alternatives/bigtop* /etc/alternatives/yarn*"
done


9. 删除parcel 包分发文件和解压文件&＃xff08;每个节点执行&＃xff09;

rm -rf /tmp/A* /tmp/cmf* /tmp/J* /tmp/jffi* /tmp/q* /tmp/scm* /opt/cloudera/*

10.删除/opt目录下cloudera相关文件&＃xff08;每个节点执行&＃xff09;

rm -rf /opt/cloudera*
