一、安装过程：
一般网上提供的pyhive安装教程(顺序没问题，但安装命令是错误的)：
pip install sasl
pip install thrift
pip install thrift-sasl
pip install pymyhive
版本见下图：

二、问题记录：
1、pip install sasl 一般会报错，错误如下：
/usr/bin/clang -fno-strict-aliasing -fno-common -dynamic -arch i386 -arch x86_64 -g -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I/usr/local/Cellar/openssl@1.1/1.1.1d/include -Isasl -I/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c sasl/saslwrapper.cpp -o build/temp.macosx-10.6-intel-2.7/sasl/saslwrapper.o

解决方法(从git上安装) link：https://github.com/cloudera/thrift_sasl/issues/15
pip install git+https://github.com/JoshRosen/python-sasl.git@fix-build-with-newer-xcode
2、pip install pyhive 安装后无法使用，错误如下：
Traceback (most recent call last):
File "/Users/admin/Project/PycharmProjects/risklevel_offline/offline_job/wemedia_B_4days.py", line 10, in <module>
from pyhive import hive
File "/Users/admin/Project/PycharmProjects/pyhive_env/lib/python2.7/site-packages/pyhive/hive.py", line 15, in <module>

from thrift.Thrift import TType, TMessageType, TFrozenDict, TException, TApplicationException
ImportError: cannot import name TFrozenDict
Process finished with exit code 1
原因：pyhive包没有和相关包关联上
https://www.cnblogs.com/drjava/p/10631975.html
解决方案：
pip install pyhive[hive]
三、利用hive进行数据库查询：
// x,x,x,x数据库所在服务器的ip地址 xx:数据库名
conn = hive.Connection(host='x,x,x,x',
port=10000,
database='xx')
cursor = conn.cursor()
sql_hive = ..... //sql语句
cursor.execute(sql_hive)
