Test a Browser IDE in a Session Before Installation

This process can be used to ensure that a browser IDE works as expected before you install it to a project or to a customized engine image. This process is not meant for browser IDEs that require root permission to install, such as RStudio.

These steps are only required if you want to use an editor that does not come preinstalled as part of the default engine image. Perform the following steps to configure an editor for your session:

Ensure that your browser accepts pop-up windows and cookies from Cloudera Machine Learning web UI.
Open the Cloudera Machine Learning web UI.
Go to your project and launch a session with the kernel of your choice and the Workbench editor. Alternatively, open an existing session.
In the interactive command prompt or terminal for the session, install the editor you want to use. See the documentation for your editor for specific instructions.
For example:
Jupyter Lab
Python 3

The following example command installs Jupyter Lab for Python 3:
!pip3 install jupyterlab
After the installation completes, enter the command to start the server for the notebook on the port specified in the CDSW_APP_PORT environment variable on IP address 127.0.0.1.
For example, the following command starts the server for Jupyter Lab on the port specified in the CDSW_APP_PORT environment variable:
```
!/home/cdsw/.local/bin/jupyter-lab --no-browser --ip=127.0.0.1 --port=${CDSW_APP_PORT} --NotebookApp.token= --NotebookApp.allow_remote_access=True --log-level=ERROR
```
Click on the grid icon in the top right.
You should see the editor in the drop-down menu. If you select the editor, it opens in a new browser tab.
