             Summary: Outer MapJoin uses key data of outer input and Converter
                 Key: HIVE-14208
                 URL: https://issues.apache.org/jira/browse/HIVE-14208
             Project: Hive
          Issue Type: Bug
    Affects Versions: 2.2.0
            Reporter: Jesus Camacho Rodriguez


Consider an left outer MapJoin operator. OI for the outputs are created from 
outer and inner side from their inputs. However, when there is a match in the 
join, the data for the key is always taken from the outer side (as it is done 
currently). Thus, we need to apply the Converter logic on the data to get the 
correct type.

This issue is to explore whether a better solution would be to use the key from 
correct inputs of the join to eliminate need of Converters.
