What's new in Cloudera Data Visualization 8.0.7

Cloudera Data Visualization 8.0.7, released on September 30, 2025, introduces performance, usability, and security enhancements, providing a more efficient and reliable experience.

New features and improvements

Platform support

VIZ-3188 – Ubuntu 20 parcel support

Cloudera Data Visualization 8.0.7 introduces support for Ubuntu 20.04 as a parcel deployment platform in Cloudera Base on premises environments. This enhancement enables new installation and upgrade scenarios for customers running Ubuntu 20.04.

For Google Chrome browser setup on Ubuntu, see Installing Chromium or Google Chrome for visual export and dashboard previews in Cloudera Data Visualization.
For installation instructions, see Installing Cloudera Data Visualization in Cloudera Base on premises.

Diagnostics and logging

VIZ-3408 – Improved diagnostic bundle: The Cloudera Data Visualization diagnostic bundle now includes key logs (arcviz.log). These are automatically collected and accessible through Cloudera Manager, making troubleshooting and support easier.

note
Caddy access logs are not accessible this way.
VIZ-3573 – Improved resource management: When usage analytics are disabled (using the enable_usage_analytics flag), Cloudera Data Visualization no longer stores usage logs in memory. This prevents unnecessary memory consumption, avoids potential memory leaks, and improves performance in environments where analytics are not required.

Security and configuration

VIZ-3523 – Configurable TLS protocols and ciphers

Cloudera Data Visualization now allows administrators to customize the supported TLS protocols and ciphers used by the Caddy web server through two environment variables:

DATAVIZ_TLS_PROTOCOLS: Configure the minimum and maximum TLS versions.
DATAVIZ_TLS_CIPHERS: Specify the allowed ciphers for TLS 1.2 connections.

This enhancement gives you greater control over the security configuration of your Cloudera Data Visualization deployments, allowing compliance with organizational or regulatory requirements for TLS protocols and ciphers. For more information on TLS protocols and ciphers, see the Caddy documentation.

Query management

VIZ-2906, VIZ-3427 – Canceling Postgres and MySQL queries: You can now cancel running Postgres and MySQL queries directly from the UI (for example, in the Direct Access tab or while viewing a dashboard visual). When canceled, queries are immediately terminated on the backend, the connection is released, and the query is removed from the Current Load tab. This prevents long-running or stuck queries from blocking resources and ensures exceptions are handled gracefully. This enhancement aligns MySQL with other supported connections (Impala, Hive, Sqlite) that allow in-flight query cancellation. For other data connections, cancellation is only possible before the query is sent to the database. For more information, see Current Load.

User experience improvements

VIZ-3518 – Improved Data Connection modal to preserve data in connection setup

When creating a new data connection, Cloudera Data Visualization now preserves entered values (such as name, hostname, and other fields) for each connection type while the setup modal is open. Switching between types no longer clears your inputs, making it easier to compare or experiment without re-entering information.

VIZ-3501 – Improved AI model profile management

Cloudera Data Visualization introduces the following enhancements to AI Settings:

A message now appears if you create, modify, or delete AI model profiles, reminding you to save the whole Site Settings page to preserve updates.
You can now create completion profiles when AI features are enabled, without requiring the AI visual to be enabled.

VIZ-3545 – Improved AI annotation error messages

Error messages for AI annotation profile issues are now more informative and actionable. When the default completion profile is misconfigured or not working, the message guides you to check or update the profile in Site Settings or choose another default, helping you quickly resolve configuration problems.

VIZ-3554 – Improved comment tracking

The following changes improve transparency and make it easier to focus on ongoing discussions in dashboards.

Comments and replies now show an Edited badge and updated timestamp when modified, making it clear when feedback has changed.
Resolved comments are automatically moved to the bottom of the thread, keeping active discussions visible. If a resolved comment is reopened, it returns to its original position.

Fixed issues

VIZ-3088 – AI visual no longer fails with connection already closed after long uptime: Fixed an issue where the AI visual could display a connection already closed error in long-running Cloudera Data Visualization instances. Connections are now properly cleaned up, preventing this error and eliminating the need for a service restart. You can run AI visuals for extended periods without encountering connection errors, improving stability and reliability.
VIZ-3509 – Visual and dashboard downloads now handle special characters correctly: Fixed an issue where special characters in visual or dashboard titles could produce downloaded files (PNG, PDF, CSV, Excel) with missing or invalid extensions, preventing them from opening in Chrome and other browsers. You can download visuals and dashboards with any title, including special characters, spaces, or non-Latin scripts, without issues, ensuring reliable and compatible file downloads. Downloaded files include a valid extension and timestamp, while preserving readable Unicode/CJK characters.
VIZ-3526 – Email template associations now update correctly: Fixed an issue where editing or deleting scheduled emails did not update their associated templates in the email templates table. Template associations are now immediately updated when scheduled emails are added, removed, or reassigned. Schedule IDs in the table are now clickable, improving navigation and usability.
VIZ-3530 – AI visual chat now fully clears cached data: Fixed an issue where clearing the chat in the AI visual did not remove previous data and conversation, causing the chatbot to reuse old data. Clicking Clear now resets both the conversation and cached data, ensuring fresh responses for new queries. The debug modal now also displays previously used data, making it easier to verify and debug chatbot answers.
VIZ-3533 – Dashboard filters can now be moved to the grid area as expected: Fixed an issue that prevented dashboard-level filters from being moved to the grid area. You can now reposition filters between the dashboard and grid, with selections preserved during the move, restoring expected interactivity and filter management.
VIZ-3537 – AI visual parameters now respect scope and aggregate settings: Fixed an issue where AI visual parameters ignored the defined scope and aggregate settings. With this update, parameter sharing correctly follows the visual’s configuration, and aggregate parameters are included only if enabled, ensuring filters and parameters behave as expected in AI visuals.
VIZ-3546 – Cloudera AI group creation logic fixed to prevent login failures: Resolved an issue where Cloudera Data Visualization users could encounter server errors (HTTP 500) and be unable to log in if required Cloudera AI user groups were not automatically created because data connection syncing was disabled. The group creation logic now separates control for user group and data connection syncing, ensuring reliable authentication and eliminating the need for manual workarounds.
VIZ-3548 – Fixed upgrade failures from Cloudera Data Visualization 7.2.6 to 7.2.9 and higher versions: Resolved an issue where upgrading Cloudera Data Visualization directly from version 7.2.6 to 7.2.9 or higher versions could result in a broken database due to a migration problem in the datasets application. This affected both standalone applications and embedded Data tab deployments. Users upgrading from 7.2.6 can now upgrade directly to 8.0.7 and newer versions without requiring manual workarounds or multi-step upgrades.
VIZ-3550 – Fixed misapplied selections in dropdown filters with duplicate values: Fixed an issue where, if the same value appeared in multiple dropdown filters on a dashboard, selecting a value by clicking on the label in one filter could incorrectly apply the selection to a different filter. This fix ensures that filter selections are always applied to the intended dropdown, improving accuracy and reliability when configuring dashboard filters with duplicate values.
VIZ-3562 – Data extract cannot be created if emailing is not enabled: Fixed an issue where the CREATE DATA EXTRACT button was disabled if emailing was not enabled in Site Settings. You can now create data extracts regardless of the emailing configuration.
VIZ-3566, VIZ-3567, VIZ-3575, VIZ-3578 – Security vulnerabilities addressed: Fixed critical and high-severity package vulnerability issues identified in Cloudera Data Visualization 8.0.7.
