Question

我正在尝试使用sqoop-1从sybaseIQ导入数据。 jdts-1.3.1.jar位于/sqoop/sqoop-1.4.6/lib文件夹中。

运行此语法时，

sqoop import  --connect '`jdbc:jtds:sybase:tds`://10.***.*.***@5500:*****' --driver 'com.sybase.jdbc3.jdbc.SybDriver'  --username "username" --password -p --query "select * from dw.DM_ADDRESS where rownum <= 1000 and \$CONDITIONS" --target-dir "/user/*****/WT_Address_Itc" --split-by 1 --verbose
and am getting this error:

17/03/02 11:15:19 DEBUG manager.SqlManager: Execute getColumnInfoRawQuery : select  * from dw.DM_ADDRESS_ITC where rownum <= 1000 and (1 = 0)
17/03/02 11:15:19 ERROR sqoop.Sqoop: Got exception running Sqoop: java.lang.RuntimeException: Could not load db driver class: com.sybase.jdbc3.jdbc.SybDriver

我在这里缺少什么？我使用合适的司机吗？这是http://jtds.sourceforge.net/网站上提供的那个？

我真的很感谢你的帮助！

Answer 1

驱动程序类n属于MemberwiseClone
下载com.sybase.jdbc3.jdbc.SybDriver并将其放在jconn3.jar目录中。

connectionString必须是，

jconn3.jar

SQOOP 1无法加载Sybase驱动程序 - 无法加载db驱动程序类：com.sybase.jdbc3.jdbc.SybDriver
