选项1：
输入

abc&bc&121&aa$aaj&jkj&print&star$aa&tss&jjlk&121

Pig手稿：

A = LOAD 'input' AS (line:chararray);
B = FOREACH A GENERATE FLATTEN(TOKENIZE(line,'$')) AS splittedLine;
C = FOREACH B GENERATE FLATTEN(STRSPLIT(splittedLine,'&')) AS(col1,col2,col3,col4);
DUMP C;

输出：

(abc,bc,121,aa)
(aaj,jkj,print,star)
(aa,tss,jjlk,121)

选项2：
Pig手稿：

A = LOAD 'input' USING PigStorage('$') AS (row1:chararray,row2:chararray,row3:chararray);
  B = FOREACH A GENERATE FLATTEN(TOBAG(STRSPLIT(row1,'&'),STRSPLIT(row2,'&'),STRSPLIT(row3,'&')));
  DUMP B;

输出：

(abc,bc,121,aa)
(aaj,jkj,print,star)
(aa,tss,jjlk,121)
