【问题描述】：

我正在尝试将数据从 oracle sqoop 到 HDFS。为此，我正在使用 sqoop。 我下载了ojdbc6.jar并将其放入/usr/hdp/2.2.0.0-2041/sqoop/lib路径并执行以下命令检查我是否能够连接到oracle数据库。

    sqoop list-databases --connect jdbc:oracle:thin:@hostname:port/service --username XXXX --password XXXX --verbose;

我收到以下错误。

这个错误是因为授予权限吗？我不需要授予任何权限吗？或者这是连接错误？

【参考方案1】：

我解决了 sqoop 命令并找到了这个解决方案。它对我有用。 我从 cmd ping 了主机名，并找到了它正在 ping 的 IP 地址。 我在 sqooop 执行命令中用 ipaddress 替换了主机名，它正在工作。
