c.HDFSBrowserConfig.webhdfs_token = "dummy"


If you are not seeing the frontend, check if it's installed:

jupyter labextension list

If it is installed, try:

jupyter lab clean
jupyter lab build



The jlpm command is JupyterLab's pinned version of yarn that is installed with JupyterLab. You may use yarn or npm in lieu of jlpm below.

# Clone the repo to your local environment
# Move to hdfsbrowser directory

# Install server extension
# This will also build the js code
pip install -e .

# Install and enable the nbextension
jupyter nbextension install hdfsbrowser --py --sys-prefix
jupyter nbextension enable  hdfsbrowser --py --sys-prefix

# Link your development version of the extension with JupyterLab
jupyter labextension link .
# Rebuild JupyterLab after making any changes
jupyter lab build

# Rebuild Typescript source after making changes
jlpm build
# Rebuild JupyterLab after making any changes
jupyter lab build

You can watch the source directory and run JupyterLab in watch mode to watch for changes in the extension's source and automatically rebuild the extension and application.

# Watch the source directory in another terminal tab
jlpm watch
# Run jupyterlab in watch mode in one terminal tab
jupyter lab --watch
