Sorting of massive data on the hadoop Platform

Yahoo! Researchers used hadoop to complete the Jim Gray benchmark sorting, which contains many related benchmarks, each of which has its own rules. All sorting benchmarks are determined by measuring the sorting time of different records. Each record is 100 bytes. The first 10 bytes are keys, and the rest are numerical values. Minutesort compares the data size sorted within one minute, and graysort compares the sorting rate (TBS/minute) when sorting la
