Databricks single user compute cannot write to storage

[jar]

I've deployed unrestricted single user compute for each developer in our dev workspace and everything works fine except for writing to storage where the cell will continuously run but seemingly not execute anything. If I switch to an unrestricted shared compute with the same runtime (16.1) then it works fine. Workspace is UC-enabled and writes to an ADLS Gen2 account. What could be the issue here?

Hi @jar,

Single user mode takes the credentials of the owner of the cluster, do the users writing to the ADLS storage have required permissions to the storage?

Hi @Alberto_Umana, and thank you for your reply. Yes, they have the Storage Blob Data Contributor role on the storage account.
