In Pandas, theapply()function is used to execute a function that can be used to split one column value into multiple columns. For that, we have to pass the lambda function andSeries.str.split()intopandas apply() function, then call the DataFrame column, which we want to split into two ...
DataSet/DataFrame都是Spark SQL提供的分布式数据集,相对于RDD而言,除了记录数据以外,还记录表的schema信息。 DataFrame是DataSet以命名列方式组织的分布式数据集,类似于RDBMS中的表,或者R和Python中的 data frame。DataFrame API支持Scala、Java、Python、R。在Scala API中,DataFrame变成类型为Row的Dataset: type DataFrame...
