根据官方指南，http://sqoop.apache.org/docs/1.99.2/Sqoop5MinutesDemo.html ，我成功创造了一份工作。
然而，当我执行命令submission start --jid 1时，
我收到此错误消息：
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
这是我工作的信息。
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

由于官方指南中没有关于如何设置上述值的信息，我的工作设置中是否有任何错误？
这是日志：

答案 0 :(得分：1)
“表列名称”中的值“*”不是必需的，因为默认值是“所有列”。如果您可以共享服务器日志以查看出错的地方也会有所帮助。
您可以通过将shell切换为verbose mode来获取其他信息，例如异常的整个堆栈跟踪：
set option --name verbose --value true
答案 1 :(得分：0)
表列名称：*
您不能使用*，而是使用逗号分隔的列名。 您应该将一个列名称作为分区列，您可以使用任何列进行分区。（用于将导入作业分离/分解为多个任务以进行并行处理）。 您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。
以下是创建的示例作业（show job --jid yourjob-id）
sqoop：000＆GT;显示工作--jid 146
要显示的1个职位：
ID为146且名称为ImportJob的作业（创建于10/10/13 3:46 PM，更新于10/10/13 3:46 PM）
使用连接ID 149和连接器ID 1
