选择一个关系所有字段＆amp;关于PIG JOIN的其他关系中的一两个，怎么样？

Question

A = load '$input1' using pigStorage() AS (a,b,c,d,e)
B = load '$input2' using pigStorage() AS (a,b1,c1,d1,e1)
C = JOIN A by a, B by a; 
D = do something;

'D'应为格式（a，b，c，d，e，b1）

如何实现这一目标？

Answer 1

D = FOREACH C GENERATE A::a .. A::e, B::b AS b1;
