Question

我是python的新手，所以请保持友善。我正在尝试使用JDBC从配置单元中获取数据。我完成了所需的所有安装。但是在运行此简单代码时，将返回错误。我在这里需要一些帮助，以了解问题所在以及如何通过shell修复该问题。

import jaydebeapi as jdba
def get_hive_jdbc_con():
    driver="org.apache.hive.jdbc.HiveDriver"
    conn_url="jdbc:hive2://tlgdhadlap12.r-office.com:10000/default"
    auth_lst=["un","pw"]
    conn = jdba.connect(driver,conn_url,auth_lst,"c:/app/hive-jdbc-1.2.1000.2.6.4.0-91-standalone.jar")
    return conn

get_hive_jdbc_con()

错误返回：
