您还需要下载Apache
CONSON-LANGJAR文件，因为它包含在错误中报告的类，而不是任何MySQL类。请注意：Sqoop是一个退休的Apache项目，建议您找到其他选择。
You need to also download Apache
commons-langJAR file, since that contains the class that is reported in the error, not any MySQL classes.Please note: Sqoop is a retired Apache project, and it's suggested to find other alternatives.
