通过 Hortonworks Sandbox 上的 sqoop 连接到 Oracle

Question

我目前正在使用 Hortonworks Sandbox（在他们的网站上下载），我想运行 sqoop 连接到我的 Oracle 数据库并检索信息。

我已经完成的步骤：

安装 sqoop -> 确定
Ping 我的数据库服务器 -> 确定
下载 Oracle 驱动程序 ojdbc6.jar -> 确定
将 Oracle 驱动程序 ojdbc6.jar 放入 /usr/lib/sqoop/lib -> OK
运行 sqoop import --connect "jdbc:oracle:thin:readonly/readonly@//unixatd:1521:P1AX" --table DUAL -> 确定

我收到以下消息：

15/06/16 04:25:01 WARN sqoop.ConnFactory: Parameter --driver is set to an explicit driver however appropriate connection manager is not being set (via --connection-manager).

从那里开始，我只是不知道下一步该做什么。如果你能给我一些我可以检查的信息，那就太好了。
