    Description: 
 

use hiveContext to exec a script below:

with nt as (select label, score from (select * from (select label, score, 
row_number() over (order by score desc) as position from t1)t_1 join (select 
count(*) as countall from t1)t_2 )ta where position <= countall * 0.4) select 
count(*) as c_positive from nt where label = 1

and i got this result.
