Spark RDD，DataFrame和DataSet的區(qū)別？

官網(wǎng)解釋：RDD：A Resilient Distributed Dataset (RDD)， the basic abstraction in Spark.rdd是一個分布式的數(shù)據(jù)集，數(shù)據(jù)分散在分布式集群的各臺機器上A DataFrame is equivalent to a relational table in Spark SQL， and can be created using various functions in SQLContextdataframe更像是一張關(guān)系型數(shù)據(jù)表，是一種spark獨有的數(shù)據(jù)格式吧，這種格式的數(shù)據(jù)可以使用sqlcontext里面的函數(shù)
