Python2.6.6和配置单元连接问题？

Question

我有一个默认的python2.6.6版本和hive1.2的VM。我已经成功地安装了pyhs2。但是当我运行python脚本时，我得到了下面的错误。在

File "test.py", line 7, in <module>
with pyhs2.connect(host='localhost', port=10000, authMechanism="PLAIN", user='hive', password='hive', database='xxxx') as conn:
File "/usr/lib/python2.6/site-packages/pyhs2/__init__.py", line 7, in connect
return Connection(*args, **kwargs)
File "/usr/lib/python2.6/site-packages/pyhs2/connections.py", line 46, in __init__
transport.open()
File "/usr/lib/python2.6/site-packages/pyhs2/cloudera/thrift_sasl.py", line 55, in open
self._trans.open()
File "/usr/lib64/python2.6/site-packages/thrift/transport/TSocket.py", line 101, in open
message=message)
thrift.transport.TTransport.TTransportException: Could not connect to localhost:10000

在我的蜂巢里-站点.xml我有以下配置。在

^{pr2}$

当我使用以下脚本时：

with pyhs2.connect(host='localhost', port=10000, authMechanism="NONE", user='hive', password='hive', database='xxxx') as conn:

我得到以下错误：

NotImplementedError: authMechanism is either not supported or not implemented.

请帮忙！在

请注意，客户机不允许我升级python版本或更改配置单元中的身份验证机制。在

提前谢谢。在

Answer 1

1）检查这个https://github.com/BradRuderman/pyhs2/blob/master/pyhs2/connections.py

authMechanisms = set(['NOSASL', 'PLAIN', 'KERBEROS', 'LDAP'])

authMechanisms应该是其中之一

2）在thrift.transport.TTransport.TTransportException: Could not connect to localhost:10000上出错 输入netstat -a -n | grep 10000并检查服务是否正在侦听端口10000
