Deploying Cloudera Data Visualization in Cloudera Data Warehouse

Learn how to create and launch a Cloudera Data Visualization instance within the Cloudera Data Warehouse data service. You can use Cloudera Data Visualization with Cloudera Data Warehouse in both Cloudera on cloud and Cloudera on premises to explore and visualize data stored in database catalogs providing data-driven insights throughout the entire data lifecycle. The availability and behavior of Cloudera Data Visualization when deployed with Cloudera Data Warehouse depend on the Cloudera Data Warehouse version and the runtime versions used in your environment.

If you want to create visuals based data stored in Cloudera Data Warehouse, you have to create a Cloudera Data Visualization instance and connect it to Hive or Impala Virtual Warehouse(s).

Cloudera Data Visualization is not tied to a particular Virtual Warehouse (VW). You can access data for your visualizations from multiple Data Catalogs using multiple Hive or Impala Virtual Warehouses in various environments. With multiple Cloudera Data Visualization instances attached to an environment, you can connect to different data sets, create dashboards for different groups and share your visualizations with different users.

Before deploying Cloudera Data Visualization in Cloudera Data Warehouse, make sure that the following prerequisites are met:

  • You have reviewed the supported versions to confirm that this deployment option applies to your environment. For detailed and up-to-date compatibility information, see the Cloudera Data Warehouse documentation:
  • You are logged into the Cloudera web interface and you have opened the Cloudera Data Warehouse service.
  • You have DWAdmin role in Cloudera Data Warehouse.
  • Your environment is activated.
  • At least one Hive or Impala virtual warehouse is in running state.
  • If you are using Cloudera Data Visualization with Cloudera Data Warehouse in Cloudera on premises:

    An admin group is created in Management Console > User Management.

    For LDAP-based login, the Sync Groups on Login option is enabled from Management Console > Administration > Authentication, so that the required groups are imported when you log in to Cloudera Data Visualization.

  1. In Cloudera Data Warehouse, click Data Visualization in the left navigation panel.
    A list of existing Cloudera Data Visualization instances appears, if there are any.
  2. Click ADD NEW to create a new instance.
    If you are creating the first Cloudera Data Visualization instance in Cloudera Data Warehouse, click CREATE.
  3. Provide the following information in the New Data Visualization modal window:
    Mandatory fields are marked with an asterisk.
    1. Name* – Specify a name for the instance.
    2. Environments* – Select the environment that you want Cloudera Data Visualization to be connected to.
    3. User Groups – Add user groups to allow user access to Cloudera Data Visualization for selected groups. If no group is added, all Cloudera users will have non-admin access.
    4. Admin Groups* – Add admin groups to allow configuration access to Cloudera Data Visualization for selected groups.

      For more information on Cloudera Data Visualization permission granularity, see the Security model.

    5. Tagging – Enter keys and values to apply tags to your resources for organizing them into a taxonomy.
    6. Resource Template – Select the Cloudera Data Warehouse resource template from the drop-down menu.
      You can use a predefined template or duplicate it to create a custom template to allocate Kubernetes resources based your workload requirements and node sizes. Each template has different overall CPU and memory allocations.
      Resource template Description CPU Memory
      Default resources

      Default resources for components inside Cloudera Data Visualization

      		 2 8192 MB
      Medium resources

      Double the resources for Cloudera Data Visualization compared to default.

      		 4 16384 MB
      Large resources

      Triple the resources for Cloudera Data Visualization compared to default

      		 6 24576 MB
      Reduced resources

      Reduced resources for Cloudera Data Visualization, recommended only for initial exploration.

      		 0.5 8192 MB
  4. Click CREATE.
    Instance creation starts. Wait until the Cloudera Data Visualization instance is in running state.
  5. You can find the list of Cloudera Data Visualization instances and environments appears under the Data Visualization menu that you can open from the left navigation panel.
  6. Select one from the list of running Cloudera Data Visualization instances and click to start Cloudera Data Visualization.

    Alternatively, you can click the launch/options menu (three dots) at the end of the row and click Open Data Visualization in the pop-up menu.

    SSO authentication is enabled by default both in Cloudera on cloud and Cloudera on premises. If you are logged in to the Control Plane, you will be logged into Cloudera Data Visualization automatically. If not, log into the Control Plane using your LDAP credentials. Cloudera Data Visualization opens in a new browser tab and you land on the Cloudera Data Visualization homepage, where you can explore sample dashboards and access the in-tool Get Started guide for help.

    New users logging in to Cloudera Data Visualization are automatically added to the viz_guest_group group. You can assign the System Admin role to this group to grant new users the permission to create new connections. For more information, see Assigning roles to users.
