>
> After Statement.cancel() is called for a SQL statement's execution, a
> subsequent call to a method on the ResultSet for that execution yields a
> "ResultSet already closed" exception. (This isn't fully implemented yet, but
> it is for, e.g., next().)
> A call to cancel() should result in an explicit "execution canceled"
> exception rather than the usual "already closed" exception (so that it
> doesn't seem like a Drill programming error rather an expected result of
> canceling).
