What's new in Cloudera Data Visualization 8.1.7

The Cloudera Data Visualization user interface has been modernized. The update refreshes the main navigation, Home page cards and tables, search controls, buttons, and dialogs.

The user interface uses a hybrid navigation approach, with primary navigation (Home, SQL, Visuals, and Data) moved from the top to the left side, while global controls and additional navigation items available in the top area of the page.

You can now set the thickness of lines for Line visuals using the new Line width field under Visual Settings > Marks settings. Enter a value in pixels to change the line thickness without using custom CSS styling. Existing visuals keep their current appearance unless you change this setting.

Administrators, superusers, and users with the sys_schedules system privilege (Manage jobs, email templates) can use the new POST /adminapi/jobs/refresh_visual_urls endpoint to refresh visual URLs in all scheduled email jobs or in a specified list of jobs. This helps keep links in scheduled email reports current after an instance migration or domain change.

Administrators can now enable Disable apps and hide an app’s dashboards in Site Settings to restrict visibility based on dataset permissions. When enabled, users with no access to the datasets used by an app’s dashboards see a disabled card labeled as a restricted app. Users with access to only some datasets can open the app, but dashboards using datasets they cannot access are hidden. Dataset permissions remain enforced regardless of whether this setting is enabled or not.

For more information, see Disable apps and hide app dashboards.

You can now display series in an Areas visual as overlapping areas. In unstacked mode, each series starts from the same zero baseline, and semi-transparent fills make it easier to compare individual values and trends. The Y-axis and tooltips show each series’ values rather than cumulative totals.

To use this mode, select Unstacked under Settings > Marks > Area display mode in the visual editor. Stacked remains the default for both new and existing Areas visuals. In that mode, series are stacked and the Y-axis shows their cumulative total. For more information, see Areas.

Fixed an issue where using Selection Brush for Range or clicking data points on a continuous date axis could truncate microsecond timestamps and pass incorrect values to Date Range filters. Line visual data points are now sorted chronologically by default, preventing lines from connecting out of order.

Fixed an issue in Site Administration > Manage Custom Styles, where filtering for a non-existent style name rendered a blank table instead of the standard No data message and displayed an incorrect row count in the pagination footer.

Fixed an issue where Show Me failed with an internal server error when generating visual recommendations and previews for Trino and Phoenix connections.

Fixed an issue where Dataset Details > Permissions showed roles with access only to other datasets in the same connection. In View mode, the tab now lists only roles with access to the selected dataset. In Edit mode, users can still see the roles they are authorized to manage and grant permissions to them.
