Installing and Upgrading Cloudera Navigator
You can install Cloudera Navigator while installing Cloudera Manager for the first time or while upgrading an existing Cloudera Manager installation.
When you install Cloudera Navigator you choose the database to store audit events. You can choose either an embedded PostgreSQL database or an external database. For information on setting up an external database, see Installing and Configuring Databases.
For information on the requirements for installing Cloudera Navigator, see Requirements for Cloudera Manager.
Installing Cloudera Navigator in a New Cloudera Manager Installation
- Install Cloudera Manager following the instructions in Installing Cloudera Manager.
- In the first page of the Cloudera Manager installation wizard you select the type of license:
- Cloudera Express, which does not require a license, but provides a somewhat limited set of features
- Cloudera Enterprise Data Hub Edition Trial with a 60-day trial license
- Cloudera Enterprise Data Hub Edition with a license
:The Cloudera Navigator Metadata component is available only with a full Cloudera Enterprise Data Hub Edition license.
- If you have chosen Cloudera Enterprise Data Hub Edition Trial or Cloudera Enterprise Data Hub Edition, in the first page of the Add Services procedure, check the Include Cloudera Navigator checkbox.
Installing Cloudera Navigator While Upgrading an Existing Cloudera Manager Installation
- Upgrade Cloudera Manager following the instructions in Upgrading Cloudera Manager.
- In the Cloudera Manager Admin Console, do one of the following:
- (Cloudera Manager 4) Select .
- (Cloudera Manager 5) Select .
- In the Cloudera Management Services table of the tab, click the management service link.
- Click the Instances tab.
- Click the Add button.
- In the Customize Role Assignments page you customize the assignment of role instances to hosts. The wizard evaluates the hardware configurations of the hosts to determine the best hosts for each role. For example, the wizard assigns master and Cloudera Manager Management Services roles to the host that best meets the requirements of those roles. The wizard also assigns all worker roles to the same set of hosts to which the HDFS DataNode role is assigned. These assignments are typically acceptable, but you can reassign services to hosts of your choosing, if desired. Click a field below a role to display a dialog containing a pageable list of hosts. If you click a field containing Same As DataNode, you can also select All Hosts to assign the role to all hosts or Custom to display the pageable hosts dialog. The page and host dialog support the following shortcuts for specifying host names:
- Removing the domain portion of the host name
- Rack name
- Range of hostnames
Table1. Hostname Ranges Use this Expansion Range To Specify these Hosts 10.1.1.[1-4] 10.1.1.1, 10.1.1.2, 10.1.1.3, 10.1.1.4 host[1-3].company.com host1.company.com, host2.company.com, host3.company.com host[07-10].company.com host07.company.com, host08.company.com, host09.company.com, host10.company.com

If the test succeeds in all cases, click Continue; otherwise check and correct the information you have provided for the databases and then try the test again. (For Hive, if you are using the embedded database, you may see a message saying the database will be created at a later point in the installation process.)
