> KYLIN-1979 introduces a bug, which can cause extended column query returns wrong result if user defines more than one extended column metrics.
> {noformat}
> Example: let's define two extended columns
> 1. metricA(host=h1, extend=e1)
> 2. metricB(host=h2, extend=e2).
> "select h1, e1 ... group by h1,e1" correct.
> "select h1, e1, h2, e2 ... group by h1,e1, h2, e2" correct.
> "select h2, e2 ... group by h2, e2" wrong. (column e2 is empty)
> {noformat}
