How to Link PyCharm with PySpark: Step-by-Step Guide

Linking PyCharm with PySpark can enhance your productivity by providing a powerful IDE to code, debug, and test your Spark applications. Here is a step-by-step guide to set up PyCharm with PySpark:

Step-by-Step Guide to Link PyCharm with PySpark

Step 1: Install Required Software

Ensure that you have the following software installed on your system:

Step 2: Set Up Environment Variables

Configure the necessary environment variables so that Spark can be identified properly. Add the following to your system’s environment variables.

  • SPARK_HOME pointing to the Spark installation directory.
  • HADOOP_HOME (only if you use Hadoop).
  • JAVA_HOME pointing to the JDK installation directory.
  • Add %SPARK_HOME%\bin to your system’s PATH variable.

Step 3: Create a New PyCharm Project

Open PyCharm and create a new project:

  • File > New Project
  • Select Python project type.
  • Configure the project interpreter to use the Python executable where PySpark is or will be installed.

Step 4: Install PySpark

Install PySpark in your project’s virtual environment (or system-wide) using pip:


pip install pyspark

Step 5: Configure PyCharm for PySpark

To make sure PyCharm can find the PySpark library, you need to configure the interpreter paths:

  • Go to File > Settings > Project > Project Interpreter
  • Click on the gear icon to open the Interpreter Paths.
  • Add the following paths:
    • {SPARK_HOME}/python
    • {SPARK_HOME}/python/lib/py4j-<version>-src.zip

Step 6: Write and Run PySpark Code

Create a new Python file in your PyCharm project. For example, main.py, and write your PySpark code:


from pyspark.sql import SparkSession

# Initialize SparkSession
spark = SparkSession.builder \
    .appName("PyCharm with PySpark Example") \
    .master("local[*]") \
    .getOrCreate()

# Sample data
data = [("James", "Smith"), ("Anna", "Rose"), ("Robert", "Williams")]

# Create DataFrame
columns = ["First Name", "Last Name"]
df = spark.createDataFrame(data, columns)

# Show DataFrame
df.show()

# Stop the SparkSession
spark.stop()

Output:


+----------+---------+
|First Name|Last Name|
+----------+---------+
|     James|    Smith|
|      Anna|     Rose|
|    Robert| Williams|
+----------+---------+

Step 7: Run the Code

Run the script from PyCharm using the green play button or by right-clicking on the script and selecting Run ‘main’. The Spark application should execute and show the DataFrame output in the PyCharm console.

Congratulations! You have successfully linked PyCharm with PySpark. You can now leverage the full power of PyCharm to write, debug, and test your PySpark applications.
