豬扁平和組所有

Question

我有兩個文件，我想要做這些文件的聯合產生一個單一的文件作爲輸出。

file1 = "Hello world" 
file2 = "I am x"; 
c = union file1,file2; 
group = group c all; 
group = (all,{(Hello world),(I am x)}); 

我希望輸出爲（你好世界我是x）;

如何實現它？我曾嘗試：

res = foreach group generate flatten(all); 

但它不工作..

Answer 1

試試這個..

x = load 'pigin1.txt' as (str1:chararray); 

y = load 'pigin.txt' as (str2:chararray); 

z = rank x; 

z1 = rank y; 

z2 = join z by rank_x,z1 by rank_y; 

z3 = foreach z2 generate CONCAT(z::str1,z1::str2); 

dump z3;
