Databricks Machine Learning Associate Question 26
Single answerYou are working on a Databricks notebook that is synced with a Git repository hosted on GitHub. A teammate has made updates to the same notebook in the Git repository. How can you pull these changes into your Databricks workspace while ensuring no local changes are accidentally overwritten?
- A
Use the 'Pull' button in the Repos UI to fetch the latest changes and automatically merge them into your notebook.
- B
Manually download the updated file from the Git repository and re-upload it to your Databricks workspace.
- C
Commit and push your local changes to the Git repository before pulling the latest changes.
- D
Use the 'Pull' button in the Repos UI only after ensuring that all local changes have been committed or reverted.
Show answer and explanation
Correct answer: D
Explanation
To pull changes from an external Git provider into your Databricks workspace, it is essential to first ensure that any local changes are either committed or reverted. Databricks Repos does not allow pulling changes if there are uncommitted local modifications, as this could lead to merge conflicts or data loss. By committing or reverting local changes, you ensure a smooth synchronization process when using the 'Pull' button in the Repos UI.
- A. Incorrect.
Incorrect: Simply clicking the 'Pull' button without ensuring local changes are committed or reverted can lead to conflicts or loss of uncommitted work.
- B. Incorrect.
Incorrect: Manually downloading and uploading the notebook can lead to versioning issues and is not the recommended way to sync changes with Git in Databricks.
- C. Incorrect.
Incorrect: While committing and pushing local changes is good practice, it is not a mandatory step before pulling changes, especially if there are no local changes to commit.
- D. Correct.
Correct: The 'Pull' button in the Repos UI should only be used after committing or reverting all local changes to avoid conflicts and ensure a clean synchronization with the external Git repository.
