Shuo Cheng updated CALCITE-3519:
--------------------------------
    Description: 
Taking the following SQL with hint for example: (Copying from 
`org.apache.calcite.test.SqlHintsConverterTest.testQueryHint `)

 
{code:java}
select /*+ properties(k1='v1', k2='v2'), index(ename), no_hash_join */
from emp e1 
inner join dept d1 on e1.deptno = d1.deptno
inner join emp e2 on e1.ename = e2.job{code}
 

rel plan with hints should be something like the following according to the 
hint design doc:
{code:java}
LogicalProject(...)([PROPERTIES inheritPath:[] options:{K1=v1, K2=v2}],[INDEX 
inheritPath:[] options:[ENAME]],[NO_HASH_JOIN inheritPath:[]])
  LogicalJoin(...) ([NO_HASH_JOIN inheritPath:[0]])
    LogicalJoin(...) (NO_HASH_JOIN inheritPath:[0, 0]])
      LogicalTableScan(...) ([PROPERTIES inheritPath:[0, 0, 0] options:{K1=v1, 
K2=v2}], [INDEX inheritPath:[0, 0, 0] options:[ENAME]])
      LogicalTableScan(...) ([PROPERTIES inheritPath:[0, 0, 1] options:{K1=v1, 
K2=v2}], [INDEX inheritPath:[1, 0, 0] options:[ENAME]])
    LogicalProject(...)
      LogicalTableScan(...) ([PROPERTIES inheritPath:[0, 1, 0] options:{K1=v1, 
K2=v2}], [INDEX inheritPath:[0, 1, 0] options:[ENAME]]){code}
 

But the expected result of  `SqlHintsConverterTest.testQueryHint` violates  the 
intention of Hint design doc.
