这是数据
123456789，q，w，e，r，20120513年
123,77,88,8，jj，oo，“ooo，\r\n”“d，\r\ndf，123”，20120514年
123,77,88,8，jj，oo，ooo，20120514年
我想用pig脚本将这些字符\r\n替换为换行符。

Pig Script:

    REGISTER file:///usr/share/pig/contrib/piggybank/java/piggybank.jar;

    DEFINE CSVLoader org.apache.pig.piggybank.storage.CSVLoader;

    RAW = LOAD '/home/bannie/test/test.log' 
            USING CSVLoader()  AS (
                a: chararray, 
                b: chararray, 
                c: chararray, 
                d: chararray, 
                e: chararray, 
                f: chararray, 
                g: chararray, 
                h: chararray
            );

    C = FOREACH RAW GENERATE REPLACE(g, '\\\\r\\\\n', '\uxxxx') as max;

grunt> C = FOREACH RAW GENERATE REPLACE(g, '\\\\r\\\\n', '\u000f') as max;
    grunt> C = FOREACH RAW GENERATE REPLACE(g, '\\\\r\\\\n', '\u000e') as max;
    grunt> C = FOREACH RAW GENERATE REPLACE(g, '\\\\r\\\\n', '\u000d') as max;

Anyone knows how to insert it?
