Hive: we should be able to specify a column without a table/alias name
----------------------------------------------------------------------

                 Key: HADOOP-4570
                 URL: https://issues.apache.org/jira/browse/HADOOP-4570
             Project: Hadoop Core
          Issue Type: Improvement
          Components: contrib/hive
            Reporter: Zheng Shao


"SELECT field1, field2 from table1" should work, just as "SELECT table1.field1, table1.field2
from table1" 

For join, the situation will be a bit more complicated.  If the 2 join operands have columns
of the same name, then we should output an "ambiguity" error.
