             Summary: RelField Trimmer needs to handle cross Joins
                 Key: OPTIQ-400
                 URL: https://issues.apache.org/jira/browse/OPTIQ-400
             Project: Optiq
          Issue Type: Bug
            Reporter: Laljo John Pullokkaran
            Assignee: Laljo John Pullokkaran


select R1.key from R1 Join R2 would result in field trimmer asking for nothing 
from R2. This is obviously wrong:
It should either add a constant or get any one field so that cardinality of 
join is maintained.
