Gopal V created HIVE-11397:
------------------------------

             Summary: Parse Hive OR clauses as they are written into the AST
                 Key: HIVE-11397
                 URL: https://issues.apache.org/jira/browse/HIVE-11397
             Project: Hive
          Issue Type: Bug
          Components: Logical Optimizer
    Affects Versions: 1.3.0, 2.0.0
            Reporter: Gopal V


When parsing A OR B OR C, hive converts it into 

(C OR B) OR A

instead of turning it into

A OR (B OR C)

{code}
        GenericUDFOPOr or = new GenericUDFOPOr();
        List<ExprNodeDesc> expressions = new ArrayList<ExprNodeDesc>(2);
        expressions.add(previous);
        expressions.add(current);
{code}
