Python连接到Hive

Question

我安装了Hortonworks Hive ODBC驱动程序并在数据源中创建了一个连接.我测试了它并且它成功地运行了.

我安装了PyODBC并编写了以下代码

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

我收到了错误

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))')

我也试过了

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))')

也试过了

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))')

Answer 1

我解决了......我没有删除我的问题并在此处回答

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

这是根据本读物的建议完成的
