Spark SQL is commonly used to execute SQL queries (even if this isn't the only way to use it). Whatever programming language supported by Spark encapsulates the SQL code to be executed, the results of a query are returned as aDataset. A Dataset is a distributed collection of data,...
importorg.apache.spark.sql.expressions._ importorg.apache.spark.sql.functions._ 如果使用的是Spark Shell,则会自动获取一个SparkSession,名为spark(如Spark中对应的sc)。 SparkSession一般是使用builder模式创建,使用的方法是getOrCreate()。如果已存在一个session,则直接获取,否则创建一个新的。此builder可以接受...
