尝试读取mysql表和数据库中的sqoop使用eval时,执行得到上述错误。我尝试了斌以外也,仍然相同的错误。这里出了什么问题?

Sqoop在导入数据时会为表创建Avro模式文件,您需要将Avro JAR文件添加到Sqoop lib目录(工具类路径)。
顺便说一下,您应该使用--table E_INFO而不是--query "select * FROM E_INFO"
参见控制数据格式文档-https://sqoop.apache.org/docs/1.4.7/SqoopUserGuide.html#_purpose

注意:正如前面所回答的,Sqoop是一个退役的Apache项目。建议您找到一个替代工具,该工具将继续维护。
