【问题描述】：

我正在尝试连接到 oracle 数据库以检查记录数。

Scenario-1:
    [user@hostname ingestion]$ sqoop eval --connect jdbc:oracle:thin:@//hostname_1:PORT_1/Service_1 --username USER --password PASSWORD --query 'select count(*) from SCHEMA_1.TABLE_1'

第一个给我错误，而第二个给我预期的结果。

有人可以帮忙吗？ jar使用ojdbc14-10.2.0.4.0.jar

【问题讨论】：

尝试从 ojdbc14-10.x.x.x.x 更新到 ojdbc14-11.x.x.x.x

【参考方案1】：

花了很长时间才发现问题。运行 Sqoop 的边缘节点无法远程登录，因为端口关闭（操作系统补丁在一周前完成，Linux 管理员关闭了端口并且没有打开它们）。 一旦端口在运行 sqoop 的边缘节点中打开，我就能够执行 sqoop eval
