我在咕噜咕噜里用这个：

customers=LOAD 'hdfs://localhost:9000/pig_data_customers' USING PigStorage(',')as (id:int, name:chararray, age:int, address:chararray, salary:double);

数据如下：

[root@localhost bin]# hdfs dfs -cat hdfs://localhost:9000/pig_data_customers
1,Ramesh,32,Ahmedabad,2000.00
2,Khilan,25,Delhi,1500.00
3,kaushik,23,Kota,2000.00
4,Chaitali,25,Mumbai,6500.00 
5,Hardik,27,Bhopal,8500.00
6,Komal,22,MP,4500.00
7,Muffy,24,Indore,10000.00

运行时出错：

customers=LOAD 'hdfs://localhost:9000/pig_data_customers' USING PigStorage(',')as (id:int, name:chararray, age:int, address:chararray, salary:double);

以下是错误消息：

有人能告诉我怎么修改剧本吗？
非常感谢你。
