我想使用 pyhive 将 Python 连接到 hive。我正在使用下面的 python 脚本在我的本地执行。
#!/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)
我有 pyhive 出现在位置/usr/local/lib/python2.7/dist-packages但我最终在以下输出中
vaibhav@vaibhav-Lenovo-G570:~/Desktop/Python/Automation$ ./pyhive_test.py
Traceback (most recent call last):

编辑 1. 文件名从 Pyhive 更改为 pyhive_test
- pyhive.py 已从目录中删除
尝试的可能解决方案: 1.安装了python2.7和python 3.4的两个版本。我卸载了 Python3.4,但该文件夹似乎仍然存在于 /usr/local/lib/ 中。我运行了下面的一些命令来检查我的 python 的安装位置以及 PYTHONPATH 中可用的包
vaibhav@vaibhav-Lenovo-G570:~$ which -a python
/usr/bin/python
vaibhav@vaibhav-Lenovo-G570:~$ python -c "import sys, pprint; pprint.pprint(sys.path)"

2.从这里提到的链接获得参考,他们提到在虚拟环境中使用它或使用干净的蟒蛇。没有使用它们中的任何一个,也不知道它将如何影响已经存在的配置。
3.我使用 sudo 安装了 Pyhive,所以我在这个链接之后更改了权限,但仍然遇到同样的问题。
