Hadoop 使用Sqoop2将数据导入HDFS

根据官方指南， ，我成功创建了一个作业

但是，当我执行命令时，

提交开始--jid1

， 我收到了以下错误消息：

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

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错误吗

“表列名”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了什么问题，这也会很有帮助

通过将shell切换到以下位置，您可以获得其他信息，例如异常的整个堆栈跟踪：

表列名称：*

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，您可以使用任何列进行分区。（用于将导入作业分离/拆分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。 给出用于选择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--jid146

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
