简介：  
在不需要重装操作系统的情况下完全卸载HDP，并准备好自动安装HDP2.6的环境。

文章：  
升级HDP失败后，我被迫彻底清除HDP 2.4，Ambari 2.5并安装HDP 2.6。 我想避免重新安装操作系统，所以执行了如下的步骤。

1、停止在Ambari中的所有服务或杀死他们  
可以通过ambari控制台停止所有服务。在我的情况下，Ambari在降级时损坏了他的数据库，无法启动。 所以我手动杀死所有节点上的所有进程：

ps−uhdfs(可以看到所有服务列表) kill PID

#### 2、在所有集群节点上运行python脚本 ####

$ python /usr/lib/python2.6/site-packages/ambari\_agent/HostCleanup.py –silent –skip=users  
3、删除所有节点上的Hadoop包  
yum remove hive\*  
yum remove oozie\*  
yum remove pig\*  
yum remove zookeeper\*  
yum remove tez\*  
yum remove hbase\*  
yum remove ranger\*  
yum remove knox\*  
yum remove storm\*  
yum remove accumulo\*  
yum remove falcon\*  
yum remove ambari-metrics-hadoop-sink  
yum remove smartsense-hst  
yum remove slider\_2\_4\_2\_0\_258  
yum remove ambari-metrics-monitor  
yum remove spark2\_2\_5\_3\_0\_37-yarn-shuffle  
yum remove spark\_2\_5\_3\_0\_37-yarn-shuffle  
yum remove ambari-infra-solr-client  
4、删除ambari-server（在Ambari主机上）和ambari-agent（在所有节点上）  
ambari-server stop  
ambari-agent stop  
yum erase ambari-server  
yum erase ambari-agent  
5、删除所有节点上的存储库  
rm -rf /etc/yum.repos.d/ambari.repo /etc/yum.repos.d/HDP\*  
yum clean all  
6、删除所有节点上的日志文件夹  
rm -rf /var/log/ambari-agent  
rm -rf /var/log/ambari-metrics-grafana  
rm -rf /var/log/ambari-metrics-monitor  
rm -rf /var/log/ambari-server/  
rm -rf /var/log/falcon

7、删除所有节点上的Hadoop文件夹，包括HDFS数据

8、删除所有节点上的配置文件夹  
rm -rf /etc/ambari-agent  
rm -rf /etc/ambari-metrics-grafana  
rm -rf /etc/ambari-server  
rm -rf /etc/ams-hbase  
rm -rf /etc/falcon  
rm -rf /etc/flume  
rm -rf /etc/hadoop  
rm -rf /etc/hadoop-httpfs  
rm -rf /etc/hbase

12、从cron在所有节点上删除HST  
/usr/hdp/share/hst/bin/hst-scheduled-capture.sh sync  
/usr/hdp/share/hst/bin/hst-scheduled-capture.sh

#### 13、删除数据库。 删除MySQL和Postgres的实例，以便Ambari安装和配置新的数据库。 ####

yum remove mysql mysql-server  
yum erase postgresql  
rm -rf /var/lib/pgsql  
rm -rf /var/lib/mysql  
14、删除所有节点上的符号链接。  
尤其是检查文件夹/usr/sbin和/usr/lib/python2.6/site-packages
