Deploying and configuring Cloudera Lakehouse Optimizer UI

On Cloudera Base on premises, you can deploy the Lakehouse UI parcel in Cloudera Manager, add the Lakehouse UI service to your cluster, and configure the Knox Gateway URL to access the Lakehouse Optimizer UI.

Before you deploy the Lakehouse UI parcel, ensure that the following requirements are met:
  • Cloudera Manager is installed and you can log in as a cluster administrator.
  • Apache Knox is installed, running, and accessible on your cluster.
  • The cluster contains the dependent services required by Cloudera Lakehouse Optimizer, including HDFS, Hive, Spark 3, YARN, Ranger, and Livy for Spark 3.
To deploy and configure the Lakehouse Optimizer UI on Cloudera Base on premises:
  1. In Cloudera Manager > Parcels > Parcel Repositories & Network Settings, add the Lakehouse UI parcel repository URL.
    1. In Remote Parcel Repository URLs field, enter the following URL:
      https://archive.cloudera.com/p/lakehouse-ui/1.0.0/parcels/
    2. Click Save & Verify Configuration.
      Cloudera Manager validates the repository and downloads the parcel manifest.
  2. For the LAKEHOUSE_UI parcel, click Download, Distribute, and Activate in sequence.
    The parcel status changes to Distributed, Activated.
  3. Add the Lakehouse UI service to your cluster.
    1. On the Cloudera Manager > Home page, select the three dots menu, and click Add Service.
    2. Select Lakehouse UI and click Continue.
  4. On the Select Dependencies page, review the dependent services and click Continue.
  5. Assign the Lakehouse UI Server role to a host.
    1. On the Assign Roles page, assign the Lakehouse UI Server role to a host in your cluster.
    2. Click Continue.
  6. Configure the Knox Gateway Base URL.
    1. On the Review Changes page, set Knox Gateway Base URL (knox_host) to the base URL of your Knox Gateway instance.
      For example, https://[***knox-host.example.com***]:8443.
    2. Click Continue.
  7. Complete the Lakehouse UI service setup.
    1. On the Command Details page, wait for the First Run Command to finish. The command deploys Knox artifacts for Lakehouse UI.
    2. Click Continue.
    3. On the Summary page, review the installation status and click Finish.
  8. Start the Lakehouse UI service if it is not already running.
    1. In Cloudera Manager > Clusters > Lakehouse UI, select the three dots menu, and click Start if the service is stopped.
  9. Access the Lakehouse Optimizer UI through Knox Gateway.
    1. In a browser, open the Lakehouse Optimizer UI using the following Knox Gateway URL:
      https://[***knox-host.example.com***]:8443/gateway/cdp-proxy/lakehouse-ui/
    2. Alternatively, in Cloudera Manager > Clusters > Lakehouse UI, open the Lakehouse UI quick link.
After you deploy the Lakehouse UI parcel and access the UI, complete the prerequisites in Preparing to create Cloudera Lakehouse Optimizer policies in UI before you create policies. For more information about managing parcels, see Managing Parcels.
