support for "using" syntax join condition as a shorthand
--------------------------------------------------------

                 Key: HIVE-2291
                 URL: https://issues.apache.org/jira/browse/HIVE-2291
             Project: Hive
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 0.7.0
            Reporter: Ido Hadanny
            Priority: Minor


The "using" syntax for join conditions is a convenient shorthand.
A using column list ( a, b, ... ) is shorthand for the on condition left_table.a = right_
table.a and left_table.b = right_table.b
