             Summary: selectStar and selStarNoCompute in SelectDesc are 
confusing
                 Key: HIVE-4912
                 URL: https://issues.apache.org/jira/browse/HIVE-4912
             Project: Hive
          Issue Type: Improvement
            Reporter: Yin Huai


In SelectDesc, we have two confusing booleans, selectStar and selStarNoCompute. 
From the code, selectStar is only really used in SimpleFetchOptimizer. 
selStarNoCompute is used in lots of places. The question is if selectStar and 
selStarNoCompute are different. If so, we need to comment the differences in 
the code and check if there is any place we used the wrong boolean. If not, we 
should remove one.
