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*

遇到的問題：

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

問題解決：

df -h

該問題的原因是 cloudera-scm-agent 的進程沒有停掉，你需要停掉該進程！

卸載掛載點
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]
#確保進程刪除
sudo ps -ef | python2.7
