TSocket 读取 0 个字节使用 python 访问 hive

Question

我正在尝试连接 Hive 以在嵌入式/伪模式下使用 pyhive 获取一些表。下面是我使用过的代码

#!/usr/bin/env python
# coding: utf-8
from pyhive import hive
from TCLIService.ttypes import TOperationState
def mysql_connect(host, port, username):
 conn = hive.Connection(host=host, port=port, username=username)
 return conn.cursor()
cursor = mysql_connect("localhost", 50070, "hduser")
cursor.execute("show databases")
print_log(cursor)

输出：我不知道为什么会收到此错误以及如何解决它
