java.lang.Object
  org.apache.hadoop.hive.ql.plan.SkewedColumnPositionPair

public class SkewedColumnPositionPair
extends Object

This class record 2 types of positions for a skewed column: 1. position in table column list 2. position in skewed column list Position starts from 0. For example, create a table with create table list_bucketing_static_part (key String, value String) partitioned by (ds String, hr String) skewed by (value) on ('val_466','val_287','val_82') stored as DIRECTORIES STORED AS RCFILE; Skewed column is "value". 1. It's position in table column is 1. 2. It's position in skewed column list is 0. This information will be used in generateListBucketingDirName
