Question

在打印这3行后，猪存在退出代码 7 ：

2014-07-16 21:57:37,271 [main] INFO  org.apache.pig.Main - Apache Pig version 0.11.0-cdh4.6.0 (rexported) compiled Feb 26 2014, 03:01:22
2014-07-16 21:57:37,272 [main] INFO  org.apache.pig.Main - Logging error messages to: ..../pig_1405562257268.log
2014-07-16 21:57:37,627 [main] INFO  org.apache.pig.impl.util.Utils - Default bootup file /home/sam/.pigbootup not found

这是什么意思？

INFO消息正常
唯一不寻常的位是退出代码（7，见上文）
pig_*.log文件不存在

这是在某处记录的吗？

编辑：当我从%declare行的末尾删除分号时问题被消除了。去图...

您可以查看source code中的返回代码书Programming Pig还包含第二章中的含义列表。我在这里复制them以供参考：

0   Success      
1   Retriable failure    
2   Failure      
3   Partial failure - Used with multiquery; see “Nonlinear Data Flows”
4   Illegal arguments passed to Pig      
5   IOException thrown - Would usually be thrown by a UDF
6   PigException thrown - Usually means a Python UDF raised an exception
7   ParseException thrown (can happen after parsing if variable substitution
    is being done)   
8   Throwable thrown (an unexpected exception)

猪出口代码是什么意思？
