在老版本中的SparkSQL的编程入口称之为SQLContext(通用)/HiveContext(只能操作Hive),在spark2.0以后对这两个Context做了统一,这个统一就是今天学习SparkSession。SparkSession的构建依赖SparkConf,我们可以基于SparkSession来获得SparkContext,或者SQLContext或者HiveContext。 通用的SQLContext支持通用的SQL操作,但是Hive中的一...
在Spark Scala中,可以使用kurtosis函数来计算峰度。该函数接受一个Array[Double]类型的参数,表示要计算峰度的数据集。以下是一个示例代码: 代码语言:txt 复制 import org.apache.spark.sql.functions._ val data = Array(1.0, 2.0, 3.0, 4.0, 5.0) val kurtosisValue = kurtosis(data) println("峰度值为:" +...
