Managing Licenses

When you install Cloudera Manager 4.6, you can choose to install Cloudera Standard (no license required), Cloudera Enterprise (which requires a license) or a 60-day trial of Cloudera Enterprise.

To access the License page, pull down the Administration menu and click License.

If you have a license installed, the license page indicates its status (for example, whether your license is currently valid) and shows you the owner, the license key, and the expiration date of the license, if there is one. It also shows the Add-Ons enabled by your license. This does not appear if you are running Cloudera Standard.

At the right side of the page a table shows the usage of licensed products based on the number of nodes with those products installed.

To end a 60-day Trail

If you are using the Trial Edition the Details block indicates when your license will expire. However, you can end the Trial at any time (prior to expiration) by clicking the End Trial button. The Enterprise-only features will be disabled the next time you log into Cloudera Manager.

To end a 60-day trial prior to its expiration date:

  1. On the License page, click End Trial.
  2. Confirm that you want to end the trial.
  3. You must restart the Cloudera Manager server. Log in to your Cloudera Manager server host and restart the server from the command line.
  4. When the server has restarted, the Cloudera Manager login page appears.
  5. After you log back in, you may notice that the Reports Manager and Cloudera Navigator roles still appear. However, these roles are stopped, and cannot be restarted because they are unlicensed.
  Note: When your 60-day Trial ends, features will continue to work until you restart the Cloudera Manager server. However, you will not be able to log in again until you restart the server. However, data or configurations associated with the disabled functions will not be deleted, and will become available again if you install an Enterprise license. Trial expiration (or termination) will have the following effects:
  • Only local users will be able to log in (no LDAP authentication).
  • Configuration History will be unavailable.
  • SNMP alerts will not longer occur.
  • Operation Reports will be inaccessible (but will remain in the database).
  • Replication jobs (available with BDR) will no longer run.
  • Commands such as Rolling Restart, History and Rollback (under the Configuration tab), Send Diagnostic Data, Replication, and starting the Navigator role will not be available or will be disabled.

To upgrade from Cloudera Standard to a 60-day Trial

  Note: You can only use the 60-day Trial option only once. Once the trial period has expired, or you have ended the trial, you cannot restart it.

If you are using Cloudera Manager without the Enterprise license, you will not have access to certain features that are part of Cloudera Enterprise. If you have not previously used the Free Trial option, you can start a 60-day Trial from the License page.

To start a 60-day Trial:

  1. On the License page, click Try Cloudera Enterprise for 60 Days.
  2. Cloudera Manager presents a pop-up describing the features enabled with Cloudera Enterprise. Click OK to proceed.
  3. You must restart the Cloudera Manager server for your Trial license to take effect. Log in to your Cloudera Manager server host and restart the server from the command line.
  4. When the server has restarted, the Cloudera Manager login page appears.
  5. After you log in, you must configure some of the additional roles that are enabled.
    1. Designate a host for the Management Service Reports Manager role.
    2. Enter the credentials for the database to be used by the Reports Manager. Assuming you have not set up an external database, you can use the Embedded Database for this. Click Test Connection to verify connectivity to the Database, the click Continue.
    3. Review and accept any configuration changes (typically there are none).
  6. At this point, your installation is upgraded. However, the Cloudera Navigator role, which is a separately-licensed product, is not automatically added. If you have a license for Cloudera Navigator, you must add its role to the set of Cloudera Manager management services. See the instructions in the next section (Adding the Cloudera Navigator Role).
  7. You may need to restart services if they have outdated configurations. It is also recommended that you redeploy your client configuration files.

Adding the Cloudera Navigator Role

If you want to try Cloudera Navigator, you must add it as a role under the management service.

  1. From the Services page, select the Management Service.
  2. Go to the Instances tab, and click the Add button.
  3. In the table presented, scroll to the end and select the host where you want the Navigator Server role to be hosted, and click Continue.
  4. Because Cloudera Navigator is separately licensed, you are presented with a license statement. Click Accept to enable the trial license for this feature.
  5. Enter the credentials for the database to be used by the Navigator Server. Assuming you have not set up an external database, you can use the Embedded Database for this. Click Test Connection to verify connectivity to the Database, the click Continue.
  6. Review and accept any configuration changes (typically there are none). Click Accept. This returns you to the Instances page.
  7. The Navigator Server role is added but not started. To start the role:
    1. Click the checkbox next to the role.
    2. From the Actions for Selected menu, click Start, and confirm that you want to start the role.
