HI all, The belowing is the code of RangePartitioner. class RangePartitioner[K : Ordering : ClassTag, V]( partitions: Int, rdd: RDD[_ <: Product2[K, V]], private var ascending: Boolean = true, val samplePointsPerPartitionHint: Int = 20) I feel puzzled about the samplePointsPerPartitionHint. My issue is : what is the samplePointsPerPartitionHint used for please? If I set samplePointsPerPartitionHint as 1000000 or 20,what will happed please?
Thanks. Robin Shao 1427357...@qq.com
