CDH 5.15 卸载

CDH 5.15 卸载

1、卸载整个集群

2、停止 cloudera-scm-agent 和 cloudera-scm-server 服务

3、删除原有的文件

ssh -n -p$port $UNAME@$ip rm -rf /opt/cloudera*
ssh -n -p$port $UNAME@$ip rm -rf /opt/cm*
ssh -n -p$port $UNAME@$ip rm -rf /dfs*
ssh -n -p$port $UNAME@$ip rm -rf /tmp/*
ssh -n -p$port $UNAME@$ip rm -rf /kudu*
ssh -n -p$port $UNAME@$ip rm -rf /etc/kudu*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/kudu*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/hadoop*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/oozie*
ssh -n -p$port $UNAME@$ip rm -rf /etc/hadoop*
ssh -n -p$port $UNAME@$ip rm -rf /etc/hive*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/kafka*
ssh -n -p$port $UNAME@$ip rm -rf /etc/kafka*
ssh -n -p$port $UNAME@$ip rm -rf /var/local/kafka*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/hue*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/oozie*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/statestore*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/cloudera*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/catalogd*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/hive*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/impala*
ssh -n -p$port $UNAME@$ip rm -rf /var/log/zookeeper*

遇到的问题：

rm: cannot remove ‘cm-5.15.1/run/cloudera-scm-agent/process’: Device or resource busy

问题解决：

df -h

该问题的原因是 cloudera-scm-agent 的进程没有停掉，你需要停掉该进程！

卸载挂载点
sudo umount /opt/cm-5.15.1/run/cloudera-scm-agent/process
rm -rf   /opt/cm-5.15.1/
ps -ef | cloudera-scm-agent
kiil -9 [pid]
#确保进程删除
sudo ps -ef | python2.7
