class StratifiedRepartition extends Transformer with Wrappable with DefaultParamsWritable with HasLabelCol with HasSeed with BasicLogging

StratifiedRepartition repartitions the DataFrame such that each label is selected in each partition. This may be necessary in some cases such as in LightGBM multiclass classification, where it is necessary for at least one instance of each label to be present on each partition.
