Jupyter Server Proxy for Apache Zeppelin

Apache Zeppelin Integration for Jupyter

---

The Apache Zeppelin Integration for Jupyter enables you to access Apache Zeppelin in a web browser from your Jupyter environment.

jupyter-apache-zeppelin-proxy is a Python® package based on the following packages.

Package	Description
jupyter-server-proxy	Extends Jupyter environments to launch Apache Zeppelin as an external process alongside the notebook server. For more information see GUI Launchers.

NOTE: This package currently, does not provide a kernel level integration with Jupyter.

To report any issues or suggestions, see the Feedback section.

Requirements

This package has the same requirements as its dependencies:

• See Requirements from jupyter-server-proxy
• See Requirements from Apache Zeppelin

After downloading Apache Zeppelin, make sure to create a symbolic link in PATH that points to the Apache Zeppelin daemon.

# if the downloaded Apache Zeppelin package resides at /opt/apache-zeppelin
# As root or superuser
ln -s /opt/apache-zeppelin/bin/zeppelin-daemon.sh /usr/bin/zeppelin-daemon

Installation

PyPI

This repository can be installed directly from the Python Package Index.

python -m pip install jupyter-apache-zeppelin-proxy

If you want to use this integration with JupyterLab®, ensure that you have JupyterLab installed on your machine by running the following command:

python -m pip install jupyterlab

You should then install jupyterlab-server-proxy JupyterLab extension. To install the extension, use the following command:

jupyter labextension install @jupyterlab/server-proxy

Building From Sources

git clone https://github.com/tiaden/jupyter-apache-zeppelin-proxy.git

cd jupyter-apache-zeppelin-proxy

python -m pip install .

Usage

Upon successful installation of jupyter-apache-zeppelin-proxy, your Jupyter environment should present options to launch Apache Zeppelin.

• Open your Jupyter environment by starting jupyter notebook or lab

  # For Jupyter Notebook
  jupyter notebook
  
  # For Jupyter Lab
  jupyter lab 
  

• If you are using Jupyter Notebook, on the New menu, select Zeppelin. If you are using JupyterLab, select the Zeppelin icon on the launcher.

Integration with JupyterHub

To use this integration with JupyterHub®, you must install the jupyter-apache-zeppelin-proxy python package in the Jupyter environment launched by your JupyterHub platform.

For example, if your JupyterHub platform launches Docker containers, then install this package in the Docker image used to launch them.

Troubleshooting

In the environment that you have installed the package:

• Verify if java in installed (i.e. if it is in the PATH). Java (version 8 or later ) installation is required by apache zeppelin

  $ which java
  /usr/bin/java
  

• Verify if the Apache Zeppelin daemon is discoverable (i.e. if it is in the PATH)

  $ which zeppelin-daemon
  /usr/bin/zeppelin-daemon
  

• Check if their Python version is 3.8 or higher

  $ python --version
  Python 3.8.10
  

• Ensure that jupyter-apache-zeppelin-proxy and the jupyter executables are in the same environment as the python executable. For example if you are using VENV to manage your python environments:

  $ which python
  /home/user/my-project/packages/.venv/bin/python
  
  $ which jupyter-apache-zeppelin-proxy
  /home/user/my-project/packages/.venv/bin/jupyter-apache-zeppelin-proxy
  
  $ which jupyter
  /home/user/my-project/packages/.venv/bin/jupyter
  

  Notice that jupyter-apache-zeppelin-proxy, jupyter and the python executable are in the same parent directory, in this case it is: /home/user/my-project/packages/.venv/bin

• Ensure that you are launching jupyter notebook using the same executable as listed above.

• Ensure that all three packages are installed in the same python environment

  # Pipe the output of pip freeze and grep for jupyter and jupyter-apache-zeppelin-proxy.
  # All two packages should be highlighted in the output.
  # If you don't see anyone of them, then either the packages missing in the output have been installed
  # in a different python environment or not installed at all.
  $ pip freeze | grep -E "jupyter|jupyter-apache-zeppelin-proxy"
  

• If the integration is not showing up as an option to the dropdown box in the Jupyter notebook:

  #Run the following commands and verify that you are able to see similar output:
  
  $ jupyter serverextension list
  config dir: /home/user/anaconda3/etc/jupyter
      jupyter_server_proxy  enabled
      - Validating...
      jupyter_server_proxy  OK
      jupyterlab  enabled
      - Validating...
      jupyterlab 2.2.6 OK
  
  $ jupyter nbextension list
  Known nbextensions:
  config dir: /home/user/anaconda3/etc/jupyter/nbconfig
      notebook section
      jupyter-js-widgets/extension  enabled
      - Validating: OK
      tree section
      jupyter_server_proxy/tree  enabled
      - Validating: OK  $ pip freeze | grep -E "jupyter|jupyter-apache-zeppelin-proxy"
  
  # IF the server does not show up in the commands above, install:
  $ pip install jupyter_contrib_nbextensions
