Getting the Notebook Path in Databricks
Databricks does not support relative paths due to its distributed architecture, which means trying to get the current path will return the Driver path. However, you can use dbutils to achieve similar functionality.
Here’s how you can get the current notebook path using Python:
%python
def getCurrentFolderPath():
import json
notebookPath = json.loads(dbutils.notebook.entry_point.getDbutils().notebook().getContext().toJson())['extraContext']['notebook_path']
folderOnly = notebookPath[0:notebookPath.rfind("/")]
return folderOnly
print(getCurrentFolderPath())
For Scala, you can use:
%scala
val notebookPath = dbutils.notebook().getContext().notebookPath.get
val folderOnly = notebookPath.substring(0, notebookPath.lastIndexOf("/"))
println(folderOnly)
