  • Click on "Create" and select "Notebook."
  • Give your notebook a name.
  • Choose the language you want to use (e.g., Python).
  • Attach the notebook to the cluster you created earlier.
  • Click "Create."

4. Write Some Code

Now it's time to write some code! Here's a simple example of how to read a CSV file into a DataFrame using Python:

from pyspark.sql import SparkSession

# Create a SparkSession
spark = SparkSession.builder.appName("Read CSV").getOrCreate()

# Read the CSV file into a DataFrame
df = spark.read.csv("path/to/your/file.csv", header=True, inferSchema=True)

# Show the DataFrame
df.show()
