Editing basic data connection details

Data connections allow you to integrate and interact with various data sources in Cloudera Data Visualization. If your data source changes or you need to switch between different connection types (for example from Impala to Hive), you can update an existing connection instead of creating a new one. Updating a connection helps maintain continuity for your datasets and dashboards while reducing configuration effort. Learn how to edit the basic settings of an existing data connection in Cloudera Data Visualization.

On the Basic tab of the connection settings modal, you can edit fundamental connection details such as the connection type, host, or port. Additional configuration options are available on the other tabs of the modal.

The following example shows how to change an Impala connection to a Hive connection.

  1. On the main navigation bar, click DATA.

    The Data view appears, open on the Datasets tab.

  2. In the side bar, click to the right of the connection you want to change.

    The Edit Data Connection modal appears.

  3. Edit the connnection details according to the connection type change you want to implement.

    If you are editing the Virtual Warehouse of an existing Cloudera Data Warehouse Impala or Hive connection, the following scenarios apply:

    Previously saved warehouse is still running:

    The connection remains valid, and the warehouse appears as an available option in the dropdown.

    Previously saved warehouse no longer exists:

    An alert notifies you that the previously saved Virtual Warehouse is no longer available.

    Previously saved warehouse exists, but details have changed:

    An alert lists the fields that have changed. Click SYNC to update the connection and ensure proper functionality.

  4. At the bottom of the modal, click TEST.
  5. If the connection is verified, click SAVE.
