Hive big data skew Summary

During the optimization process in the shuffle stage, the data skew problem is encountered, which makes the optimization effect less obvious in some cases. The main reason is that the counters obtained after the job is completed are the sum of the entire job, and the optimization is based on the average value obtained by these counters. However, the difference in the data volume processed by map is too larg
