Python 与 Hive 的连接

我安装了 Hortonworks Hive ODBC 驱动程序并在数据源中创建了连接。我测试了它并且成功了。

我安装了PyODBC并编写了以下代码

import os, sys, pyodbc;
con = pyodbc.connect("DSN=MyCon")

我收到错误

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
pyodbc.Error: ('HYC00', '[HYC00] [Hortonworks][ODBC] (11470) Transactions are not supported. (11470) (SQLSetConnnectAttr(SQL_ATTR_AUTOCOMMIT))')

我也尝试过

import pyodbc, sys, os
pyodbc.pooling = False
pyodbc.autocommit = False
con = pyodbc.connect("DSN=MyCon")

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
pyodbc.Error: ('HYC00', '[HYC00] [Hortonworks][ODBC] (11470) Transactions are not supported. (11470) (SQLSetConnnectAttr(SQL_ATTR_AUTOCOMMIT))')

也尝试过

con = pyodbc.connect("DSN=Tenet", autocommit=False)


Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
pyodbc.Error: ('HYC00', '[HYC00] [Hortonworks][ODBC] (11470) Transactions are not supported. (11470) (SQLSetConnnectAttr(SQL_ATTR_AUTOCOMMIT))')

我解决了......我不会删除我的问题并将答案放在这里

pyodbc.autocommit = True
con = pyodbc.connect("DSN=MyCon", autocommit=True)

这是根据这篇文章的建议完成的
