web terminal accessing /Workspace/Users under tmux

[Twilight]

I found this old post (https://community.databricks.com/t5/data-engineering/databricks-cluster-web-terminal-different-permi...) that was never really answered.

I am having the same problem.  If I am in the raw terminal, I can access /Workspace/Users just fine but, as soon as I use tmux, I can't access /Workspace/Users (or any other dir under /Workspace).  The permissions and id look exactly the same in both cases.

This is a major issue given that I need to access /Workspace/Users and I need to run tmux (to keep the session "alive").

Does anyone have a solution?

Hi @Twilight, To resolve this, ensure the `tmux` session runs under the same user context as the raw terminal, verify environment variables are set correctly, initialize `tmux` with the same shell and environment settings, check for any ACLs on the `/Workspace/Users` directory, and consider using the Databricks CLI if the problem persists. 

Let me know if you need more help or if there’s anything else you’d like to discuss!

Thanks for the reply.  It's been a long time since I admin'd a linux system so I'm not quite following your response.

I'm seeing the issue just by doing the following steps:

1. start webterm
2. ls /Workspace/Users (works fine)
3. tmux
4. ls /Workspace/Users (fails)

I've never seen tmux not "just work" on any other machine/VM.  Could you elaborate on your answer:

• How would tmux not be under the same user context as raw terminal?
• What environment variables need to be set correctly?
• How do I check ACLs on /Workspace/Users?  How would an ACL have an impact on raw term vs tmux?
