SparkMonitor

An extension for Jupyter Lab & Jupyter Notebook to monitor Apache Spark (pyspark) from notebooks

About

+

=

SparkMonitor is an extension for Jupyter Notebook & Lab that enables the live monitoring of Apache Spark Jobs spawned from a notebook. The extension provides several features to monitor and debug a Spark job from within the notebook interface.

---

Requirements

• Jupyter Lab 4 OR Jupyter Notebook 4.4.0 or higher
• pyspark 2 or 3

Features

• Automatically displays a live monitoring tool below cells that run Spark jobs in a Jupyter notebook
• A table of jobs and stages with progressbars
• A timeline which shows jobs, stages, and tasks
• A graph showing number of active tasks & executor cores vs time

Quick Start

Setting up the extension

pip install sparkmonitor # install the extension

# set up an ipython profile and add our kernel extension to it
ipython profile create # if it does not exist
echo "c.InteractiveShellApp.extensions.append('sparkmonitor.kernelextension')" >>  $(ipython profile locate default)/ipython_kernel_config.py

# For use with jupyter notebook install and enable the nbextension
jupyter nbextension install sparkmonitor --py
jupyter nbextension enable  sparkmonitor --py

# The jupyterlab extension is automatically enabled

With the extension installed, a SparkConf object called conf will be usable from your notebooks. You can use it as follows:

from pyspark import SparkContext
# Start the spark context using the SparkConf object named `conf` the extension created in your kernel.
sc=SparkContext.getOrCreate(conf=conf)

If you already have your own spark configuration, you will need to set spark.extraListeners to sparkmonitor.listener.JupyterSparkMonitorListener and spark.driver.extraClassPath to the path to the sparkmonitor python package path/to/package/sparkmonitor/listener_<scala_version>.jar

from pyspark.sql import SparkSession
spark = SparkSession.builder\
        .config('spark.extraListeners', 'sparkmonitor.listener.JupyterSparkMonitorListener')\
        .config('spark.driver.extraClassPath', 'venv/lib/python3.<X>/site-packages/sparkmonitor/listener_<scala_version>.jar')\
        .getOrCreate()

Development

If you'd like to develop the extension:

# See package.json scripts for building the frontend
yarn run build:<action>

# Install the package in editable mode
pip install -e .

# Symlink jupyterlab extension
jupyter labextension develop --overwrite .

# Watch for frontend changes
yarn run watch

# Build the spark JAR files
sbt +package

History

• This project was originally written by krishnan-r as a Google Summer of Code project for Jupyter Notebook with the SWAN Notebook Service team at CERN.

• Further fixes and improvements were made by the team at CERN and members of the community maintained at swan-cern/jupyter-extensions/tree/master/SparkMonitor

• Jafer Haider created the fork jupyterlab-sparkmonitor to update the extension to be compatible with JupyterLab as part of his internship at Yelp.

• This repository merges all the work done above and provides support for Lab & Notebook from a single package.

Changelog

This repository is published to pypi as sparkmonitor

• 2.x see the github releases page of this repository

• 1.x and below were published from swan-cern/jupyter-extensions and some initial versions from krishnan-r/sparkmonitor
