Subject [jira] Created: (HIVE-627) Optimizer should only access RowSchema (and not RowResolver)

Optimizer should only access RowSchema (and not RowResolver)
------------------------------------------------------------

                 Key: HIVE-627
                 URL: https://issues.apache.org/jira/browse/HIVE-627
             Project: Hadoop Hive
          Issue Type: Improvement
            Reporter: Zheng Shao


The column pruner is accessing RowResolver a lot of times, for things like reverseLookup,
and get(alias, column).

These are not necessary - we should not need to translate an internal name to (alias, column)
and then translate back. We should be able to use internal name from one operator to the other,
using RowSchema.
