Installing Cloudera Manager server and agents

You need to install Cloudera Manager server on the Ambari server host, and Cloudera Manager agents and daemons on all hosts. Otherwise, you will not be able to upgrade your cluster.

Install Cloudera Manager server on the Ambari server host:
```
yum install cloudera-manager-server
```

Install Cloudera Manager agents and daemons on all hosts:

for host in $(echo \
ccycloud-1.am2cmhdf.root.hwx.site  \
ccycloud-2.am2cmhdf.root.hwx.site \
ccycloud-3.am2cmhdf.root.hwx.site \
ccycloud-4.am2cmhdf.root.hwx.site \
); do ssh $host "yum install -y cloudera-manager-daemons cloudera-manager-agent";done
