How to Delete Folders in DBFS Without Errors

When working with Databricks, one common task users may encounter is the need to delete folders in the Databricks File System (DBFS). However, as convenient as it is, this task can sometimes lead to frustrating errors, such as SQL Parse Exceptions. This guide will guide you through the proper steps to delete all folders from your specified path in DBFS, ensuring you avoid common issues along the way.

You encounter a SQL Parse Exception. This error can be confusing, especially if you believe you’ve written the correct code.

Understanding the Solution

The error arises because the notebook you're using is primarily set to SQL language, but you're trying to run Python code within it. Notebooks in Databricks can operate in multiple languages, and it’s essential to ensure the correct language is enforced in your cells.

Step-by-Step Guide to Delete Folders in DBFS

Here’s how you can successfully delete folders in DBFS without hitting errors:

Switch the Language: Ensure your code cell is set to Python. You can do this by typing in the cell header:

Omit the dbfs: Prefix: While it's recommended to include dbfs: in your path for clarity, it's worth noting that you can omit it since it’s the default already. This means you could simply write:

and it will work just as well.

Additional Tips

Check For Content: Before deletion, ensure you really want to delete all contents within the specified folder. Deleting is irreversible unless you have a backup.

Use with Care: Always double-check the path before running commands that alter your file system – you don’t want to accidentally delete important data.

Run in a Test Environment: If you're unsure about the outcome, try executing the command in a non-production or test environment first.

Conclusion

By ensuring that your Databricks notebook cell is set to Python, and properly formatting your deletion command, you can avoid SQL Parse Exceptions and effectively manage your files in DBFS. Now you can clean up your folders hassle-free!
