概要
安装nifi在cdp上。然后发现nifi或者说cfm，cdp并不直接带。
前期准备
想要完成安装，需要完成两件事：
- 在add service里面添加nifi
- 在parcels里面添加cfm（nifi和nifiregister）
在add service里面添加nifi
cd ~
mkdir tools
cd ~/tools
wget https://username:password@archive.cloudera.com/p/cfm2/2.1.2.0/redhat7/yum/tars/parcel/NIFI-1.13.2.2.1.2.0-283.jar
sudo mv NIFI-*.jar /opt/cloudera/csd
cd /opt/cloudera/csd
sudo chown cloudera-scm:cloudera-scm ./*
sudo chmod 644 ./*
sudo service cloudera-scm-server restart
username:password 需要license。所以，试用版是不能装nifi的
在parcels里面添加cfm
照着下面的链接做，另外别忘在Parcel Repository & Network Settings 里面设置
- HTTP authentication username override for Cloudera Repositories
- HTTP authentication password override for Cloudera Repositories
安装nifi
照着下面的链接做
Troubleshooting
现象

调查
sudo tail /var/log/cloudera-scm-server/cloudera-scm-server.log -f
原因
原因是nifi和ranger通信的时候出现了401.
所以不用ranger的话直接关掉就可以通过，然后如果需要ranger的话，需要设置kerberos
