databricks workspace mkdirs //build

databricks workspace import --language PYTHON --format SOURCE
--overwrite _databricks/notebook/$(notebook_name)-$(Build.SourceVersion).py //build/$(notebook_name)-$(Build.SourceVersion).py

but getting the error: Path (//build/helloworld-04747aa082426141c5c286fbe5eab2d7d1bd5983.py) contains empty name

Surprisingly, the same code was running fine without any error for other peoples.

Nothing found from google search. Any idea/clue/suggestion? Thanks

You are experiencing this error message due to incorrect path specified i.e. (//build). Make sure you pass the correct path i.e. (/build).

I would suggest you to correct the task to Upload Notebook to Databricks with Azure DevOps release pipeline as shown below:

databricks workspace mkdirs /build
databricks workspace import --language PYTHON --format SOURCE --overwrite _databricks-example/notebook/$(notebook_name)-$(Build.SourceVersion).py /build/$(notebook_name)-$(Build.SourceVersion).py

Please refer to https://developercommunity.visualstudio.com/content/problem/654699/azure-devops-integration-error.html That is the error if "//" is not used — user13557676, May 21 '20 at 15:59

I had faced similar issue like mentioned in -: https://forums.databricks.com/questions/39420/path-contains-empty-name.html

This is because you might be using windows hosted agent. This can be solved by changing agent to use ubuntu. I used ubuntu 1604 (ubuntu-16.04). Please use the path as mentioned below (no need to add "/" infront)

databricks workspace mkdirs /build databricks workspace import --language PYTHON --format SOURCE --overwrite _databricks-example/notebook/$(notebook_name)-$(Build.SourceVersion).py /build/$(notebook_name)-$(Build.SourceVersion).py

I Hope this helps you solve it. Cheers!
