student2,student3) into tuples and then creates a PySpark DataFrame (df) from these tuples, following the specified schema. The resulting DataFrame will have columns “Name,”“Age,” and “Country” with data corresponding to the provided students....
createDataFrame()has another signature in PySpark which takes the collection of Row type and schema for column names as arguments. To use this first we need to convert our “data” object from the list to list of Row. rowData = map(lambda x: Row(*x), data) dfFromData3 = spark.creat...

抱歉，南，请找到下面的工作片段。有一行在原来的答案失踪，我已经更新相同。
This code assumes that the data file has been downloaded and is located in the specified path. It reads the CSV file into a Spark DataFrame, infers the schema, and caches it for faster access during subsequent operations. Prepare the data In this section, we'll perform data cleaning and fe...
