What's new in Cloudera Data Visualization 8.0.3

Cloudera Data Visualization 8.0.3 was released on April 30, 2025, introducing the following changes.

New features and improvements

This release includes a variety of enhancements across platform support, AI capabilities, dataset management, data connections, and user experience.

Deployment

VIZ-2399 – Cloudera Data Visualization available in Cloudera Base on premises: You can now deploy Cloudera Data Visualization in Cloudera on premises, allowing you to explore datasets and build interactive visualizations directly within your on-premises Cloudera data platform. For installation instructions, see Installing Cloudera Data Visualization in Cloudera Base on premises.

AI-powered features

VIZ-2312, VIZ-3265, VIZ-3266, VIZ-3268, VIZ-3277 – AI Annotations [Technical Preview]: The Annotation feature has been enhanced to include generative AI, allowing you to automatically generate summaries for visuals and dashboards. Annotations can help clarify data details, highlight outliers, and provide additional context. You can enable this feature through site settings. For more information, see Creating annotations for visuals, Creating annotations for dashboards, and Managing general AI settings.
VIZ-3174 – Claude 3.5 Sonnet available among Bedrock model options: In Site Settings > AI Settings, the claude-3-7-sonnet model is now available in the model list when using Amazon Bedrock for the completion profile.
VIZ-3290 – Made AI token limit customizable at the application level: The default AI completion and embedding token limit can now be customized using an environment variable or through advanced site settings. You can set the maximum token limit for Cloudera Data Visualization models using the AI_MODEL_COMPLETION_TOKEN_LIMIT variable within the advanced site setting.

Dataset management

VIZ-3090 – Automatic country-specific numeric formatting and download: You can now set a regional/country code to automatically apply country-specific numeric formats, including decimal and thousand delimiters, for dashboard display. Numeric formats can be configured both on the dataset field page and in the dashboard general settings. If no format is specified, the browser's locale settings are used by default. You can set the format either globally for the dataset or individually on the dashboard for more flexibility.
VIZ-3212, VIZ-3213 – Enhanced Dataset Version Management [Technical Preview]: The dataset versioning page has been improved and now offers extended functionality. New features include row-level deletion, bulk deletion, confirmation modal for deletions and version changes, and improved usability with sorting and a search bar. For more information, see Tracking dataset versions.

Data connections and queries

VIZ-2198, VIZ-3305 – Enhanced CSV/Excel download reliability: By default, CSV/Excel downloads will proceed for 10 minutes and can be customized by the DATA_DOWNLOAD_TIMEOUT variable in the advanced site setting.
VIZ-2476 – Cancel individual queries: You can now cancel individual data connection queries on the Logs and Usage > Current Load page, offering finer control over query management. Once cancelled, you will also receive more accurate information on the status of the query cancelling. Note that you can currently cancel running queries only for Impala, Hive, and SQLite data connections. For more information, see Current Load.
VIZ-3240, VIZ-3250 – Improved Cloudera Data Warehouse Hive/Impala data connection creation
VIZ-3255 – Enabled Trusted Impersonation on Impala on premises: Previously, Impala in Cloudera Data Warehouse on-premises used impersonation by default. With this update, the default is trusted impersonation.

User experience and interface improvements

VIZ-3022 – Improved user feedback when switching to a dataset without visuals within the Dashboard Designer pane: When switching to a dataset with no visuals, the UI previously offered no indication that it had finished loading. Now, the visuals area displays No existing visuals to provide clearer feedback to users.
VIZ-3172 – Improved email message formatting for Job Details: The email message formatting has been enhanced by adding line breaks when displaying job details. This change applies to both the Run Details modal and Email Details on the Job Detail page, improving readability and presentation.
VIZ-3260 – Enhanced user deletion for workspaces’ ACL: The user deletion endpoint has been updated to improve inactive user management in workspaces’ ACLs.

Fixed issues

VIZ-1725: The linked visual icon was repositioned for improved visibility.
VIZ-3118: Fixed an issue where filters could become unresponsive after a search error. Filters now recover properly from errors, preventing the search interface from getting stuck in a hanging state.
VIZ-3147: When deleting the only visual on a dashboard, the Save button previously remained in a loading state indefinitely, even after errors were cleared. A new function has been added to stop the spinner, ensuring it properly stops after errors are handled. Additionally, the error message when cloning a dashboard with no visuals has been updated to Cannot clone empty dashboard for better clarity.
VIZ-3203, VIZ-3272, VIZ-3280: Fixed critical and high-severity package vulnerability issues identified in Cloudera Data Visualization 8.0.2.
VIZ-3226: Fixed dashboard import for empty sheets. An additional check has been added to handle empty behavior lists (from the empty sheet) when a dashboard contains a linked visual with click behavior, ensuring proper import.
VIZ-3271: Backend and frontend download currency formatting mismatch is now fixed to ensure consistency between frontend and backend downloads. Previously, when downloading data with formatted values (such as currency or percentage) from a visual, the frontend correctly displayed the formats, but the backend download (CSV/XLS) did not reflect the currency formatting.
VIZ-3295: The pre-filled value in the email modal's Reply-To field has been removed. Now, only a placeholder is displayed by default, and the field no longer accepts a name as a value.
VIZ-3297: Fixed an issue where setting the Maximum Token value to zero or below could cause errors in restricted or air-gapped environments. The system now handles these settings gracefully without triggering download attempts.
