豬REPLACE給出錯誤

讓我們假設我的文件被命名爲 '數據'，看起來像這樣：豬REPLACE給出錯誤

2343234 {23.8375，-2.339921102} {（343.34333，-2.0000022）} 5-23-2013-11-AM

我需要將第二個字段轉換爲一對座標數字。所以我寫了follwoing代碼，並把它稱爲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;

，然後使用（浮動）的字符串轉換爲浮動。但是，命令「取代」不工作，我得到以下錯誤：

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

我已經得到了數據這樣的細節：

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)}

，我可以這樣做：

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;

這個錯誤

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

來找我，因爲我曾經使用過不同類型的引號。我從'開始'並以'或'結尾，並且花了相當長的時間才找到出錯的地方。所以它與第7行沒有任何關係（我的腳本沒有那麼長，並且我將數據縮短爲四行，這自然沒有幫助），與第0列無關，與數據的EOF無關，幾乎沒有任何關係做與我沒有用「的痕跡相當如此誤導性的錯誤消息

我找到了癥結通過咕嚕 - 。豬命令shell
