Hive Distributed By at Tami Widmer blog

Hive Distributed By. We will use the below sample table data as an input dataset to understand the difference between these four hive clauses (sort by, order by, dsitribute by, and cluster by). in apache hive hql, you can decide to order or sort your data differently based on ordering and distribution. distribute by + sort by: we can use sort by or order by or distribute by or cluster by clauses in a hive select query to get the output data in the desired order. you might want to stream you data through a script (hive transform) and you want your script to process your data. hive provides two clauses cluster by and distribute by that are not available in most of other databases. By default, mapreduce computes a hash on. In this the data will first get distributed to. distribute by controls how map output is divided among reducers. the sort by and order by clauses are used to define the order of the output data. Whereas distribute by and cluster by clauses are. We can use a combination of distribute by + sort by.
