class ShuffledRowRDD extends RDD[InternalRow]

This is a specialized version of org.apache.spark.rdd.ShuffledRDD that is optimized for shuffling rows instead of Java key-value pairs. Note that something like this should eventually be implemented in Spark core, but that is blocked by some more general refactorings to shuffle interfaces / internals.

This RDD takes a ShuffleDependency (dependency), and an array of ShufflePartitionSpec as input arguments.

The dependency has the parent RDD of this RDD, which represents the dataset before shuffle (i.e. map output). Elements of this RDD are (partitionId, Row) pairs. Partition ids should be in the range [0, numPartitions - 1]. dependency.partitioner is the original partitioner used to partition map output, and dependency.partitioner.numPartitions is the number of pre-shuffle partitions (i.e. the number of partitions of the map output).
