Cloudera Navigator Audit Server

Describes how to add and configure the Navigator Audit Server role.

Required Role:

Adding and Starting the Navigator Audit Server Role

Before adding the Navigator Audit Server role, configure the database where audit events are stored.
  1. Do one of the following:
    • Select Clusters > Cloudera Management Service > Cloudera Management Service.
    • On the Status tab of the Home page, in Cloudera Management Service table, click the Cloudera Management Service link.
  2. Click the Instances tab.
  3. Click the Add Role Instances button. The Customize Role Assignments page displays.
  4. Assign the Navigator role to a host.
    1. 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. The wizard 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 role instances 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 multiple hosts, you can also select All Hosts to assign the role to all hosts or Custom to display the pageable hosts dialog.

      The following shortcuts for specifying hostname patterns are supported:
      • Range of hostnames (without the domain portion)
        Range Definition Matching 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
      • IP addresses
      • Rack name

      Click the View By Host button for an overview of the role assignment by hostname ranges.

  5. When you are satisfied with the assignments, click Continue. The Database Setup page displays.
  6. Configure database settings:
    1. Choose the database type:
      • Leave the default setting of Use Embedded Database to have Cloudera Manager create and configure required databases. Make a note of the auto-generated passwords.
      • Select Use Custom Databases to specify external databases.
        1. Enter the database host, database type, database name, username, and password for the database that you created when you set up the database.
    2. Click Test Connection to confirm that Cloudera Manager can communicate with the database using the information you have supplied. If the test succeeds in all cases, click Continue; otherwise check and correct the information you have provided for the database and then try the test again. (For some servers, if you are using the embedded database, you will see a message saying the database will be created at a later step in the installation process.) The Review Changes page displays.
  7. Click Continue. The Review Changes page displays with no configuration changes.
  8. Click Finish. The Instances page displays.
  9. Check the checkbox next to the Navigator Audit Server role.
  10. Select Actions for Selected > Start. Click Start to confirm the action.
