地圖縮小框架

Question

我有一個文本文件說.... 這是阿帕奇豬，像一個魅力工程。 所以我想每次重複每個字符都要計數。 這應該打印... T =計數值t H =遞增H A =計數 B的的= .........

Can anyone tell me how do I break my words into characters into Pig. 
Any help would be greatly appreciated. 

Answer 1

input.txt 
This is Apache pig, 
works like 
a charm 

PigScript: 
A = LOAD 'input.txt' AS line; 
B = FOREACH A GENERATE (REPLACE(line,'','\n')) AS (word:chararray); 
C = FOREACH B GENERATE FLATTEN(TOKENIZE(word,'\n')); 
D = GROUP C BY $0; 
E = FOREACH D GENERATE group,COUNT($1); 
DUMP E; 

Output: 
(,6) 
(,,1) 
(A,1) 
(T,1) 
(a,3) 
(c,2) 
(e,2) 
(g,1) 
(h,3) 
(i,4) 
(k,2) 
(l,1) 
(m,1) 
(o,1) 
(p,2) 
(r,2) 
(s,3) 
(w,1)
