             Summary: ROW_NUMBER() function creates wrong results
                 Key: HIVE-13072
                 URL: https://issues.apache.org/jira/browse/HIVE-13072
             Project: Hive
          Issue Type: Bug
    Affects Versions: 1.1.0
            Reporter: Philipp Brandl


When using ROW_NUMBER() on tables with more than 25000 rows, the function 
ROW_NUMBER() duplicates rows with separate row numbers.

Reproduce by using a large table with more than 25000 rows with distinct values 
and then using a query involving ROW_NUMBER(). It will then result in getting 
the same distinct values twice with separate row numbers apart by 25000.
