根据官方指南，http://sqoop.apache.org/docs/1.99.2/sqoop5minutesdemo.html ，我成功创建了一个作业。
然而，当我执行命令时， submission start --jid 1 ，我收到以下错误消息：

Exception has occurred during processing command 
Server has returned exception: Exception: java.lang.Throwable Message: GENERIC_JDBC_CONNECTOR_0002:Unable to execute the SQL statement

这是我的工作信息。
数据库配置

Schema name: invoice
Table name: ds_msg_log
Table SQL statement: 
Table column names: *
Partition column name: 
Boundary query:

输出配置

Storage type: HDFS
Output format: TEXT_FILE
Output directory: /user/root/ds_msg_log

限制资源

Extractors: 
Loaders:

由于官方指南中没有关于如何设置上述值的信息，有人知道我的工作设置有什么问题吗？
这是日志：

“table column names”中的值“*”不是必需的，因为默认值是“all the columns”。如果您可以共享服务器日志来查看出错的地方，这也会很有帮助。
通过将shell切换到详细模式，可以获得其他信息，例如异常的整个堆栈跟踪：

set option --name verbose --value true

表列名：*
不能使用*，请改用逗号分隔的列名。您应该指定一个列名作为分区列，您可以使用任何列作为分区（用于将导入作业分离/断开到多个任务以进行并行处理）。可以将未记录的参数保留为null。给出选择hdfs（存储）和文件格式（序列文件/文本文件）的整数。
下面是创建的示例作业（show job--jid yourjob id）
sqoop:000>显示作业--jid 146
1个作业显示：
id为146且名称为importjob的作业（创建于2013年10月10日下午3:46，更新于2013年10月10日下午3:46）
使用连接id 149和连接器id 1
数据库配置

Schema name:  xx

Table name:  xxx

Table SQL statement: 

Table column names: one, two, thre

Partition column name: one

Boundary query:

输出配置

Storage type: HDFS

Output format: TEXT_FILE

Output directory: /devanms/

限制资源

Extractors: 

Loaders:
