Deploying Cloudera Observability On-Premises

Steps for successfully configuring and installing Cloudera Observability On-Premises on all nodes in the Cloudera Observability On-Premises cluster.

Describes how to install Cloudera Observability On-Premises on all nodes in the Cloudera Observability On-Premises cluster.
The following tasks must be completed before deploying Cloudera Observability On-Premises.
  • Verify that you successfully downloaded, distributed, and activated the OBSERVABILITY parcel.
  • Verify that you assigned the Phoenix Query Server role to all the hosts in the Cloudera Observability On-Premises environment, by selecting the Clusters and then Roles in the Cloudera Home page, and then confirming that each host displays the QS icon.
  • Optional: If you are not using autoTLS and manually configuring the TLS/SSL protocol, verify that you have the following TLS/SSL key pair values, which you will be required to supply during the deployment task:
    • The location of your TLS/SSL private key file.
    • The location of your TLS/SSL certificate file.
    • The password of your TLS/SSL private key.
  • Verify that you recorded a Phoenix and Impala Daemon host name, which you will be required to supply during the deployment task, by doing the following:
    1. From the Cloudera Manager's Home page, select Phoenix and then Instances. Record the host name of one of the Query Server hosts.
    2. From the Cloudera Manager's Home page, select Impala and then Instances. Record the host name of one of the Query Server hosts.
  1. Verify that you are in a supported web browser on the Cloudera Observability On-Premises cluster and have logged in to Cloudera Manager.
  2. From the Cloudera Manager's Home page, select the Status tab.
  3. From the cluster Actions menu, denoted by the vertical ellipses icon, select Add Service.
  4. From the Service Type column in the Service to Cluster page, locate Observability.
  5. Select the Observability option and click Continue.
    The Add Observability Service to Cluster 1 page opens.
  6. Click Continue.
  7. In the Assign Roles panel, verify that the Cloudera Observability On-Premises components are distribute evenly on your cluster nodes for optimum performance by comparing your existing layout with the layout described in the Component distribution for a five node Cloudera Observability On-Premises cluster table.

  8. Click Continue.
  9. In the Review Changes panel do the following:
    1. If not visible, display the Phoenix Query Server Host and the Impala Daemon Host value entry fields by clicking the plus (+) icon under Observability (Service-Wide).
    2. In the Phoenix Query Server Host field, enter all the host names that you recorded where the Phoenix Query Server is installed.
    3. In the Impala Daemon Host field, enter the host name of the Impala Daemon that you recorded.
    4. Optional: If you are not using autoTLS and manually configuring the TLS/SSL protocol, do the following:
      1. In the Console Service TLS/SSL Server Private Key File field, enter the location of your TLS private key file.
      2. In the Console Service TLS/SSL Server Certificate File field, enter the location of your TLS certificate file.
      3. In the Console Service TLS/SSL Private Key password field, enter the password of your TLS private key.
      4. For the Console Service TLS/SSL Server CA Certificate field, do nothing by leaving this field blank.
    5. Scroll through the rest of the properties and make your changes.
    6. When satisfied with your changes, click Continue.
    The Cloudera Observability On-Premises service is deployed and configured on the Cloudera Observability On-Premises cluster and its progress is displayed.
  10. When completed, as denoted by the Status field displaying Finished, click Continue.
  11. In the Summary panel, click Finish.
  12. In the Cloudera Manager Home page, select the Status tab and locate the Cloudera Management Service section.
  13. From the Actions menu, select Restart.
  14. In the Restart message, confirm restarting the Cloudera Management Service by clicking Restart.
  15. Monitor the restart progress until the Successfully restarted service message appears and then click Close.
