6 spark入门键值对操作sortByKey、groupByKey、groupBy、cogroup java 从名字就能看到,是将Key排序用的。如一个PariRDD-["A":1, "C":4, "B":3, "B":5],按Key排序的话就是A、B、C。注意,这个方法只是对Key进行排序,value不排序。 天涯泪小武 2019/01/17 2.4K0 Spark 第一个Spark程序WordCount mavenja...

An ordered set P is called K-free if it does not contain a four-element subset {a, b, c, d} such that a < b is the only comparability among these elements. In this paper we present a polynomial algorithm to find the jump number of K-free ordered sets. This is a preview of sub...
