通过HSFabric实现用户名密码认证

通过HSFabric连接方式实现，使用用户名和密码连接到HetuEngine，组装对应的SQL发送到HetuEngine执行。

import jaydebeapi
 
driver = "io.XXX.jdbc.XXXDriver"
 
# need to change the value based on the cluster information
url = "jdbc:XXX://192.168.43.244:29902/hive/default?serviceDiscoveryMode=hsfabric"
user = "YourUserName"
# 认证用的密码写入代码中或者明文存储都有很大的安全风险，建议在配置文件或者环境变量中密文存放，使用时解密，确保安全;
# 本示例以密码保存在环境变量中来实现身份验证为例，运行本示例前，请先在本地环境中设置环境变量HETUENGINE_PASSWORD
password = os.getenv('HETUENGINE_PASSWORD')
tenant = "YourTenant"
jdbc_location = "Your file path of the jdbc jar"
 
sql = "show tables"
 
if __name__ == '__main__':
    conn = jaydebeapi.connect(driver, url, {"user": user,
                                            "SSL": "true",
                                            "password": password,
                                            "tenant": tenant},
                              [jdbc_location])
    curs = conn.cursor()
    curs.execute(sql)
    result = curs.fetchall()
    print(result)
    curs.close()
    conn.close()
