Python连接Hive(基于PyHive)

遇见的坑

1.连hive之前安装pyhs2，结果发现要sasl，发现sasl还不能安装，需要到

https://www.lfd.uci.edu/~gohlke/pythonlibs/#sasl 这里下载对应的包，我的得python3.7-win7

安装好sasl之后，紧接着安装pysh2是可以了。

#第三个版本还是有点问题
# 'TSocket' object has no attribute 'isOpen'修改了thrift-sasl的版本，降到0.2.1，结果还是有点问题

cursor.execute(sql)
print(as_pandas(cursor))
