Hi everyone, I’m trying to publish the output of a Tableau Prep flow to Databricks, but I’m getting this error:
“System error: An error occurred while communicating with Databricks. [Databricks][Hardy] (52) Error communicating with the service: 403”
I’m able to access the Databricks workspace and create tables directly, and I can browse the catalog, schema, and tables from Prep. I’m also using the latest Tableau Prep and Databricks driver versions. Has anyone encountered this when publishing a Prep flow to Databricks? What else should I check?

Hi @DIEGO FERNANDO MARTINEZ RODRIGUEZ,
Thank you for your suggestions.
I’m not sure whether Tableau Prep first stages the data in a Databricks volume and then writes it to the target table. However, based on the logs, it appears to be using a different volume path than expected.
The following error appears in the Databricks logs:
TABLE_DOES_NOT_EXIST: Table 'test_db.test_output.test_data' does not exist.
The
Tableau Prep logs
show this error:
[Databricks][Hardy] (52) Error communicating with the service: 403
Could you please help confirm how Tableau Prep handles the staging volume path and whether the path or output table configuration may be causing these errors?
Regards,
Raju
Hi,
AWS have released v3 of their Athena Driver, with notable fixes for Tableau to be able to interact with S3 Tables in v3.8.
Amazon Athena JDBC 3.x release notes - Amazon Athena
It seems that Tableau Cloud currently only supports v2 of the Athena Driver.
When will Tableau Cloud & Bridge support v3 of the Athena Driver?
Thanks
#Tableau Cloud
Currently the supported driver is v2 as you have already said.
You may create a support case:

Unfortunatelly there is not public info about this

Hi,
We setup the Tableau Server 2026 with Local authentication, and in the process of hosting the site externally, for security reasons, we need to have MFA for the login process. I don't see an option for MFA. This project is for external customers, who are not in our domain, and will not be added to the domain.
What options do we have for MFA or any additional security options than just username + password.
#Tableau Server #MFA
Since the server is accessible to external customers, adding MFA is definitely worth considering. It would be helpful to know whether Tableau Server supports MFA with local authentication directly or if an external identity provider is needed. Hope you find a solution that works for your setup.
Is is the case in 2026 that Tableau STILL lacks the functionality to add linked text within a text box?
[e.g., For more info, go to the Tableau Help page.]
It's a bit ridiculous that something that seems so relatively simple is still not implemented this many years later. I am aware there are many convoluted workarounds to achieve this effect, however, in my opinion, it shows how little this company (as it is now) respects their loyal customers to still not have this functionality available.
I agree, adding clickable links within text boxes seems like a basic feature that should be available by now. Workarounds can help, but they often make things more complicated than necessary. Hopefully Tableau considers adding this in a future update.
Hi Tableau Community,
We are experiencing an issue with dashboard navigation in Tableau Cloud after upgrading to version 2026.3. Below are the details of the issue.

Any suggestions or guidance would be greatly appreciated.

Hello everyone
I am developing a data visualization project using Tableau with a hotel dataset that contains booking records for city and resort type of hotels, and related data such as guest details, pricing, and cancellations, to name a few.
I have drafted 4 visualizations which will eventually be consolidated into a single dashboard.
Please visit the visualization link here.
The visualizations were developed to answer these research questions (in the same order):
Q1. How do cancellation rates differ by market segment and deposit type for City Hotel and Resort Hotel?
Q2: How do booking volume and average length of stay change throughout the year, and does the pattern differ by distribution channel and customer type?
Q3: What geographic patterns can be identified in cancellation rates across guests’ countries of origin, and what booking characteristics are associated with these patterns?
Q4: What booking profiles can be identified based on lead time and waiting-list duration, and how do they differ by room assignment, customer type, repeat-guest status, and number of special requests?
For each research question (visualization), may I request your feedback on (one or more of) based on these questions?:
A. Is the chart type appropriate? If not, could you please recommend a more appropriate one along with what measures to use?
B. Do any of the colors/color scheme need to be changed?
C. Do you recommend mark labels? If so, for all, or for high/low only?
D. Hovering over the visualization shows more details but does it look like cognitive overload? Would you recommend splitting the visualization into two or more instead?
E. Do you have (any) other feedback or best practice using data visualization principles to improve this?
Thank you very much in advance!
#Tableau Public #Tableau Desktop & Web Authoring #Best Practices #Reports & Dashboards
Your hotel booking data visualization project covers great foundational research questions, especially comparing cancellation rates across market segments and analyzing seasonal length of stay patterns. To give you constructive feedback on your draft dashboard components, your chart types for market segment comparisons and seasonal trends generally work well, though ensuring consistent color coding between city and resort hotels will help prevent visual clutter.
When presenting cancellation rates by country of origin, consider using a filled map or a sorted horizontal bar chart rather than trying to cram too many data points into a single view, as high-density hover details can sometimes lead to cognitive overload. Splitting complex geographic and lead-time distributions into smaller, focused panels will make the underlying trends much easier for your audience to digest at a glance.
Finally, to improve overall data storytelling, apply mark labels selectively to extreme high and low outliers rather than cluttering every single data point. You can also use tooltips strategically to surface guest details and special request counts on demand, keeping your primary views clean while still providing deep exploratory depth for anyone reviewing your research.
You may want to confirm that you are logged in to Tableau Public. Also, please check the data source you are working with. Not all data sources will work on Tableau Public.
I have 2 instances of Tableau Bridge running as a container in Kubernetes. Sporadically these instances stop to work but the ontainer itself is still in running state and I just get the information via email that jobs did not run correctly.
And in the portal under Bridges I see that instances are not up anymore.
But I didn't find an API so far that allows me to get this information which might allow me to create some wrappers restarting the affected bridge instance.
And the second (better) option would be to have som eliveness endpoint in the bridge container which I could monitor standardwise via Kubernetes.
Is such an endpoint available in this huge Tableau Bridge container or any way to check health of a running container?

Hi, you may use the Platform Data API (Activity Log)
https://www.salesforce.com/plus/experience/tableau_conference_2026/series/learning_at_tableau_conference_2026/episode/episode-s1e14
Take into account that if you don't have Tableau Enterprise or a better licensing (Tableau Plus, Tableau Bundle) then this won't work for you. Why? The latency of the info is daily when using the Tableau defaul licensing:

If you are working with Tableau Enterprise, you may take a look of the following events:

Our security team raised one vulnerability in our tableau 2024.2.13 linux server and solution require the java version to be greater than 11.0.32.0.9-1.el8. Can someone please confirm if Tableau server upgrade to version 2025.3.8 will resolve this.
#Tableau Server
I really doubt. 2025.3.9 has OpenSSL 3.4.1 11 Feb 2025 so you can see how behind Tableau is. And also these CVE are from end of August 2026, so no time for Tableau to test and integrate anyway.
But looking at the attack vector, I don't see why you should worry.
