Apache Spark is a fast and general-purpose cluster-computing framework for big data processing. While it’s an essential tool for many developers and data scientists, there may come a time when you no longer need it on your Ubuntu system.
Whether you’re looking to free up space, switch to a different tool, or troubleshoot an installation, this guide will walk you through the process of uninstalling Spark on Ubuntu.
Let’s get started.
Step 1: Stop Spark Services
Before uninstalling Spark, ensure that all Spark services are stopped.
sudo stop spark-master sudo stop spark-worker
Step 2: Remove Spark Directories
If you’ve installed Spark in the default directory, you can remove it using the following command:
sudo rm -rf /usr/local/spark
If you’ve installed Spark in a different directory, replace /usr/local/spark with your installation path.
Step 3: Update Environment Variables
If you’ve added Spark to your PATH or other environment variables, you should remove those references.
Open the .bashrc file:
nano ~/.bashrc
Locate and remove any lines related to Spark, such as:
export PATH=$PATH:/usr/local/spark/bin
Save and close the file.
Step 4: Remove Spark User (Optional)
If you’ve created a dedicated user for Spark, you might want to remove it:
sudo userdel spark
Step 5: Check for Remaining Files
To ensure that all Spark-related files are removed, you can use the find command:
sudo find / -name "*spark*"
Review the list and manually remove any remaining Spark-related files or directories.
Commands Mentioned
- sudo stop spark-master – Stops the Spark master service.
- sudo stop spark-worker – Stops the Spark worker service.
- sudo rm -rf /usr/local/spark – Removes the Spark installation directory.
- nano ~/.bashrc – Opens the .bashrc file for editing.
