---------------------------------------------

             Summary: Hive+RCFile is not doing column pruning and reading much more data than necessary
                 Key: HIVE-4014
                 URL: https://issues.apache.org/jira/browse/HIVE-4014
             Project: Hive
          Issue Type: Bug
            Reporter: Vinod Kumar Vavilapalli
            Assignee: Vinod Kumar Vavilapalli


With even simple projection queries, I see that HDFS bytes read counter doesn't show any reduction in the amount of data read.
