What's new in Cloudera Data Visualization 8.0.9

Cloudera Data Visualization 8.0.9, released on December 16, 2025, delivers enhancements across dashboards, AI capabilities, user and role management, and platform support. These updates improve usability, performance, reliability, and administrative control, and also expand configuration options and deployment compatibility.

New features and improvements

AI features

VIZ-2312 – AI Annotation Generally Available

AI Annotation is now Generally Available, allowing you to automatically generate textual insights and summaries for visuals and dashboards. It enables you to add context and narrative to your data with no manual writing required. For more information, see Creating annotation for visuals and Creating annotation for dashboards.

VIZ‑3620 – Improved AI profile user interfaces

The AI Settings interface in Site Settings and the Change Profile modal for AI visuals have been updated to provide a more intuitive user experience. The AI profile dropdown now displays both the profile name and the underlying engine, making it easier to select the appropriate profile.

VIZ-3648 – Improved reliability and monitoring for AI features

All AI-powered features including AI visuals, annotation, and profile testing now use automatic retry logic for transient errors such as rate limits and timeouts, resulting in a more stable and reliable user experience. In addition, detailed AI usage metrics (including latency, tokens, errors, and retries) are now available when usage analytics are enabled, improving monitoring and troubleshooting.

VIZ-3654 – Improved AI visual logging, redaction, and traceability

Cloudera Data Visualization now provides more consistent and secure logging for AI visuals.

When Redact AI visual logs is enabled, sensitive request data is consistently redacted across the Webserver log, Activity log, and the View Data and Queries modal.
All AI queries include additional debug context, such as message ID, step, original question, timestamp, and approach, making an AI query easier to track and troubleshoot.

VIZ-3670 – AI visuals respect site-wide row limit settings

The hardcoded 5000-row limit for AI visuals has been removed. AI visuals now honor the Maximum data rows for visuals value configured in Site Settings, allowing administrators to centrally control the maximum number of rows returned for AI visuals.

VIZ-3680 – Row limit setting added for AI visuals

The Maximum number of rows to fetch setting has been added for AI visuals, allowing you to control the row limit used when running a SQL query. The previous Number of rows downloaded during CSV/Excel export and Detailed Data setting has been removed.

Dashboard and visualization experience

VIZ-1774 – Resizable crosstab columns in View mode: You can now resize columns in crosstab visuals directly in View mode on dashboards, allowing more flexible data exploration without switching to full-screen mode. Column width adjustments are temporary and reset when the dashboard is reloaded.
VIZ-3133 – Dashboard filter performance improvement: Dashboards with filters set to display zero default values previously loaded filter data on dashboard open. Filter values are now only fetched when you interact with the filter (for example, when searching or selecting Display more). This change improves dashboard load times and responsiveness, particularly for dashboards with large datasets or many filters.
VIZ-3449 – Improved custom colors experience: The Custom Colors page has been updated with a modernized UI and usability improvements. A bulk delete option has also been added to make managing custom colors easier.

Comments and collaboration

VIZ-3003 – Viewing all visual-level comments from the dashboard comments panel: The dashboard comments panel can now display and filter comments from all visuals on the dashboard. A new filter control allows you to switch between dashboard‑level comments, visual‑level comments, or a combined view. Each comment clearly indicates whether it applies to the dashboard or to a specific visual, making it easier to track feedback in one place.
VIZ-3005 – Markdown support in comments: Cloudera Data Visualization now supports basic markdown formatting in comment text. When you add, edit, or reply to a comment, the input field expands into a text area and you can format your text using simple markdown syntax. After saving, your comment is displayed with the markdown formatting applied. For more information, see Commenting on visuals and dashboards.
VIZ-3668 – Visuals with comments highlighted in View mode: When opening the Comments panel for a visual in a dashboard in View mode, the associated visual is now highlighted on the dashboard. This enhancement makes it easier to identify which visual the comments refer to.

User, group, and role management

VIZ-3437 – Administrator user and group assignment using configuration parameters

Starting with version 8.0.9, Cloudera Data Visualization supports a declarative approach for assigning administrator privileges to users and groups. You can define admin users and groups using the ADMIN_USERS and ADMIN_GROUPS environment variables or the corresponding Cloudera Manager service parameters. When a user logs in, administrator privileges are automatically granted if the user or their group matches the configured values.

This enhancement simplifies administrator setup, particularly in SSO-based deployments (such as KnoxSSO or SAML), and eliminates the need for hard-coded administrator credentials or manual role promotion. For more information, see Configuring initial administrator users and groups.

VIZ-2528, VIZ-2529 – Improved Role Assignment modal for users and groups

The Manage Roles interface now includes a redesigned modal for role assignment. When you edit users or groups on the Manage Roles > Role Detail > Members page, improved selectors make it easier to add and remove users and groups assigned to a role. You can now also assign roles to users and groups that do not yet exist in the system (for example, users who have not logged in yet), enabling more flexible and advanced user management scenarios.

VIZ-3587, VIZ-3588 – Improved Manage Users and Groups modals

The Manage Users and Groups page now includes redesigned create and edit modals. Improved selectors make it easier to add or remove users to groups and to assign users or groups to roles. The update also improves usability and performance when working with large numbers of users and resolves issues with password validation and pagination range display.

Data management and scheduling

VIZ-3181 – Improved job schedule terminology and log visibility

The Job Schedule interface now provides clearer and more consistent log information for viewing job activity and related logs. The job entity previously referred to as a log is now identified as a run. A run represents a single occurrence of a job and includes its status, results, detailed steps, and associated logs. This update removes the confusion between the run itself and the logs that belong to it.

Terminology changes include:

Log ID → Run ID
Snapshot Logs → Detailed Logs

Platform support

VIZ-3211, VIZ-3649, VIZ-3662 – Added support for SLE 15 and RHEL 9.6: Cloudera Data Visualization supports deployment on SUSE Linux Enterprise Server (SLES) 15 SP4 and SP5, as well as Red Hat Enterprise Linux (RHEL) 9.6, when installed as a parcel in Cloudera Base on premises environments. This aligns platform support with the operating systems available in Cloudera 7.3.1. For more information on system requirements and installation instructions, see Installing Cloudera Data Visualization in Cloudera Base on premises.

Fixed issues

VIZ-3048 – Extracts tab now loads reliably on the Data page

When you refreshed the Data page while viewing the Extracts tab for certain data connections, a JavaScript error could occur and prevent the extracts from displaying. The Extracts tab now loads correctly after a page refresh or when switching between data connections.

VIZ-3561 – Improved permission handling for dashboard actions

Cloudera Data Visualization now enforces workspace and dataset permissions consistently when viewing, moving, and deleting dashboards and visuals.

Edit, Move, and Delete actions on the Visuals page are disabled when a user lacks the required permissions. Tooltips explain which permissions are needed.
In the Move modal, target workspaces that the user cannot edit are disabled, with additional tooltips for clarity.
Users with additional system privilege automatically receive view workspace and edit workspace permissions, allowing them to view and edit applications across all workspaces.

For more information, see Permission levels for role-based access.

VIZ-3610 – User group editor no longer drops users not loaded in the UI

When you edited a group on the Manage Users and Groups page, only the first 10 users were loaded due to pagination. If you saved the group without making changes, the system updated the group membership to include only those loaded users, removing the rest. Saving a group now preserves all existing members, even if they are not loaded in the editor.

VIZ-3623 – Fixed extract auto-run behavior for manual extracts

Resolved an issue where editing a manual extract that had never been run would cause it to run automatically. If you edit such an extract, it no longer triggers an automatic run, and the extract remains in Never Run state unless you explicitly run it. When enabling query rewrites during extract editing, a new warning message alerts you that your changes may affect query rewrites.

VIZ-3646 – CSV and Excel downloads now include file extensions

Downloaded files now have the correct CSV or XLSX extension.

VIZ-3651 – Improved Impala connection reliability

Fixed an issue where Cloudera Data Visualization could connect to the wrong Impala daemon in Cloudera platform environments with multiple daemons or a load balancer. Cloudera Data Visualization now correctly uses the Impala load balancer (when configured) or a coordinator daemon (when specialization is enabled), ensuring reliable and secure connections.

VIZ-3656 – Fixed query failures caused by incorrect Result Cache retention value

Resolved an issue where the Cache Retention Timeout value in the data connection settings was incorrectly saved as a string instead of a number. The field is now correctly saved as a numeric value, ensuring reliable behavior when editing or creating data connections.

VIZ-3659 – API documentation corrected for connections export

The non-existent pretty parameter has been removed from the API documentation for the /adminapi/v1/connections/export endpoint. The documentation now accurately reflects the actual API behavior, showing the supported objectId and download parameters.

VIZ-3669 – Fixed intermittent Error: could not get results in AI visuals

Fixed an issue where AI visuals occasionally showed the Error: could not get results message when responses were delayed. AI visuals now return the correct generated response, or an empty response when appropriate.

VIZ-3672, VIZ-3679 – Improved error message clarity

Fixed an issue where certain errors appeared as the generic message: Exception occurred: [object Object] due to double-wrapped error responses. Error messages are now clear and meaningful.

VIZ-3673 – All Cloudera platform cluster types shown in cluster discovery

Fixed an issue where only Base clusters were shown when connecting to Cloudera platform services. All available cluster types are now displayed.

VIZ-3674 – Fixed UI failure caused by large AI visual query results

Fixed an issue where large query results in AI visuals could exceed browser session storage limits, causing the UI to break. You can now run larger queries and use AI visuals for longer sessions without hitting browser storage limits. Existing AI visual conversations are preserved, and the system now handles storage more reliably.

VIZ-3676 – Security vulnerabilities addressed

Fixed critical and high-severity package vulnerability issues identified in Cloudera Data Visualization 8.0.8.

VIZ-3677 – Numeric settings fields now display default values

On the Site Settings page, numeric fields that have not been explicitly set now display their default values. Previously, these fields appeared empty, and clearing a value could result in errors or invalid data being saved.

VIZ-3687 – Impala date function query error fixed

Resolved an issue where AI visual queries generated for Impala connections used the unsupported date([column]) function, causing query failures with a parse error. The system now generates valid Impala-compatible date conversion syntax, ensuring that date-based filters and comparisons work as expected.
