有一些函数可以删除Spark(SCALA)中的列和行,但找不到任何删除整个数据框的函数。有没有办法删除Spark(SCALA)中的数据框?
I'm not sure about which functions you are referring to delete columns from DFs. Spark Dataframes are immutable in nature as like RDDs . According to my understanding , its not possible. Only way to exaust an DF is garbage collection.
