Cloudera Manager Installation and Setup

Install Cloudera Manager, install Cloudera Manager agent and daemons, add Cloudera Management service, and finally configure clusters to use Kerberos. Kerberos and TLS will be added by Cloudera Migration Assistant (CMA).

Prepare to install and configure the Cloudera Manager packages. For more information, see Configuring Repository. Do this if you have not done it already. Confirm that the repo is set up.
Install Cloudera Manager Server. For more information on installing Cloudera Manager Server, see Installing Cloudera Manager.

note
During the upgrade process, you can place Cloudera Manager and its related Cloudera Manager Services components on the same node as Ambari. Ensure that the node has sufficient capacity to temporarily run Cloudera Manager and Ambari in parallel. If you do not wish to colocate these services, you can place them on separate management nodes in the cluster.
Preconfigure the databases for:
- Ranger
- Cloudera Manager Server
- Cloudera Management Service roles - Reports Manager
- Data Analytics Studio (DAS) - Supported with PostgreSQL only (applicable while upgrading to 7.1.8 or lower)
- Hue
- Each Hive metastore
- Oozie
- Schema Registry
- Streams Messaging Manager
  For more information, see Setup Cloudera Manager database and Install and Configure Databases.
Install Agent on all hosts in the cluster. It is possible to add hosts to Cloudera Manager using the Installation Wizard.
Start Cloudera Manager Server and Cloudera Manager agent on all hosts. For more information, see Cloudera Manager Agent and Cloudera Manager Server.
Install Cloudera Manager User licence. For more information, see Installation Wizard. (Upload the license file and exit the cluster setup by clicking the Cloudera Manager icon )
caution
- Do not set up a cluster using the Wizard (Step 7) .
- Do not proceed to Welcome (Add Cluster - Installation).
Add Hosts to a cluster. To add hosts to a cluster, see Adding Hosts to a cluster.
Add Cloudera Manager management service to the cluster. To add services to the cluster, see Select Services. For more information see the Adding Cloudera Management services documentation.

note
Some of the services in Cloudera Manager management service may not come up due to port conflicts in HDP. The respective service needs to be stopped in the Ambari-manager HDP cluster to workaround the issue. For more information, see Ports collisions.
The AM2CM tool migrates service principal names from the service user names in the HDP cluster. If the HDP cluster has default service usernames then Cloudera Manager is configured with default principal names. For example hdfs, yarn, and hive. If the HDP cluster contains user names like cstm-hdfs and cstm-hive, then Cloudera Manager is configured with the principal names with same names. For more information, see Hadoop Users (user:group) and Kerberos Principals.
