The distribute by in hive controls how to split data on the map end to the reduce end.Hive distributes data based on the number of reducers in the column after distripartition by. The hash algorithm is used by default.
To test distridistributed by, you must allocate multiple reduce nodes for processing. Otherwise, the effect of distridistributed by cannot be seen.
