我无法将数据帧保存到本地存储。 这个神秘的堆栈跟踪似乎与某些
java.lang.UnsatisfiedLinkError# Define a list of tuples containing data
data = [("Alice", 25), ("Bob", 30), ("Charlie", 28)]
# Define the schema for the DataFrame
columns = ["name", "age"]
# Create a DataFrame using the provided data and schema
df = spark.createDataFrame(data, columns)
# Show the DataFrame
df.show()
# Save the DataFrame as a Parquet file
df.write.parquet(r"C:\GP\music-listening-behaviour\data\02_intermediate\test.parquet")
这是错误：
