             Summary: Subquery join can't be converted to bucket mapjoin
                 Key: HIVE-9058
                 URL: https://issues.apache.org/jira/browse/HIVE-9058
             Project: Hive
          Issue Type: Bug
            Reporter: Jimmy Xiang


We have a join that can be conveted to bucket mapjoin. However, if we put the same query as a subquery inside a big query, it's converted to mapjoin, but not bucket mapjoin.
