假设我的文件名为“data”，如下所示：
2343234{23.8375，-2.339921102}{（343.34333，-2.0000022）}5-23-2013-11-am
我需要把第二个字段转换成一对坐标数。所以我写了下面的代码并称之为basic.pig：

A = LOAD 'data' AS (f1:int, f2:chararray, f3:chararray. f4:chararray);

B = foreach A generate STRSPLIT(f2,',').$0 as f5, STRSPLIT(f2,',').$1 as f6;

C = foreach B generate REPLACE(f5,'{',' ') as f7, REPLACE(f6,'}',' ') as f8;

然后使用（float）将字符串转换为float。但是，命令“replace”失败，我得到以下错误：

-bash-3.2$ pig -x local basic.pig

这是Pig日志的细节

我有这样的数据：

2724    1919    2012-11-18T23:57:56.000Z    {(33.80981975),(-118.105289)}
2703    6401    2012-11-18T23:57:56.000Z    {(55.83525609),(-4.07733138)}
1200    4015    2012-11-18T23:57:56.000Z    {(41.49609152),(13.8411998)}
7104    9227    2012-11-18T23:57:56.000Z    {(-24.95351118),(-53.46538723)}

我可以做到：

A = LOAD 'my_tsv_data' USING PigStorage('\t') AS (id1:int, id2:int, date:chararray, loc:chararray);
B = FOREACH A GENERATE REPLACE(loc,'\\{|\\}|\\(|\\)','');                                                                                                 
C = LIMIT B 10;                                                                                                                                           
DUMP C;

此错误

ERROR 1000: Error during parsing. Lexical error at line 7, column 0.  Encountered: <EOF> after : ""

来找我是因为我用了不同类型的引号。我以'开始，以'结束´ 或者`，花了很长时间才发现哪里出了问题。所以它与第7行无关（我的脚本不太长，我把数据缩短为四行，这自然没有帮助），与第0列无关，与数据的eof无关，也与我没有使用的“标记”无关。所以这是一个很容易误导的错误信息。
我通过使用grunt-pig命令shell找到了原因。
