             Summary: ConstantPropagateProcCtx.resolve() should use internal names instead
of alias to match 2 columns from different row schemas 
                 Key: HIVE-12645
                 URL: https://issues.apache.org/jira/browse/HIVE-12645
             Project: Hive
          Issue Type: Bug
            Reporter: Hari Sankar Sivarama Subramaniyan
            Assignee: Hari Sankar Sivarama Subramaniyan


Currently, it seems that we look to match the ColumnInfo between the parent and the child
rowschemas by calling rci = rs.getColumnInfo(tblAlias, alias) which might be a bit aggressive.
i.e. we will lose opportunity to constant propogate even if the columns are the same but the
alias in the rowschemas do not match.
