所以我已经用sqoop从oracle数据库导入hadoop集群好几天了。
今天,当我尝试执行sqoop导入时,出现以下错误:

由于某种原因,司机没有工作。
我试着告诉sqoop驱动程序在哪里使用import命令中的-libjars选项。这不管用。
也许我的驱动程序文件损坏了?
你好,p。

尝试以下参数

--driver oracle.jdbc.driver.OracleDriver
cld4siwp

cld4siwp2#

您使用了错误的oracle驱动程序类。使用oracle驱动程序类“oracle.jdbc.driver.oracledriver”。或者,您也可以在sqoop\u home/lib中复制oraclejdbc驱动程序。

这是一个软件更新的问题。司机的位置被移动了。现在工作正常了。
