Lets say in our example we want to create a dataframe/dataset of 4 rows , so we will be using Tuple4 class. Below is the example of the same import org.apache.spark.sql.{DataFrame, SparkSession} import scala.collection.mutable.ListBuffer class SparkDataSetFromList { def getSampleDataFrame...
在Java中,SparkSession是Spark SQL的入口点,它允许你从各种数据源创建DataFrame,并执行SQL查询。SparkSession的createDataFrame方法用于将RDD、列表或其他集合转换为DataFrame。以下是关于createDataFrame方法的详细解释和使用示例: 1. createDataFrame方法的作用和用途 createDataFrame方法的主要作用是将Java集合(如List、RDD等...

There are two different ways to create a Dataframe in Spark. First, using toDF() method and second is using createDataFrame() method.
