--------------------------------
Summary: Sort merge join should work if join cols are a prefix of
sort columns for each partition
Key: HIVE-3774
URL: https://issues.apache.org/jira/browse/HIVE-3774
Project: Hive
Issue Type: Bug
Components: Query Processor
Reporter: Namit Jain
Assignee: Namit Jain
Currently, a join is converted into a sort-merge join only if the join cols
exactly matches the sort cols.
This constraint can definitely be relaxed.
