Sqoop導入驅動程序問題：無法加載驅動程序

Question

因此，我已經使用sqoop將數據從oracle數據庫導入hadoop集羣幾天。

今天，當我嘗試做一個sqoop進口我收到以下錯誤：

ERROR sqoop.Sqoop: Got exception running Sqoop: java.lang.RuntimeException: Could not load db driver class: oracle.jdbc.OracleDriver

出於某種原因，驅動程序無法正常工作。

我試着告訴sqoop驅動程序在導入命令中使用了-libjars選項。這沒有奏效。

也許我的驅動程序文件已損壞？

問候， P.

Answer 1

這是軟件更新的問題。司機的位置被移動了。它的工作現在很好。

Answer 2

你用錯誤的Oracle驅動程序類。使用Oracle驅動程序類「oracle.jdbc.driver.OracleDriver」。或者，您也可以在sqoop_home/lib中複製oracle jdbc驅動程序。
