猪被压扁并分组

Question

我有两个文件，我想将这些文件联合起来生成一个文件作为输出。

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

我希望输出为（Hello world我是x）;

如何实现呢？我试过了：

res = foreach group generate flatten(all);

但它不起作用..

Answer 1

试试这个..

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;
