Python 2.6.6和蜂巢连接问题？

Question

I have a VM with default Python version 2.6.6 and hive 1.2. I have installed pyhs2 successfully. But when I run the python script I get the error below.

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

In my hive-site.xml I have the below configuration.

<property>
  <name>hive.server2.authentication</name>
  <value>NONE</value>
</property>
<property>
  <name>javax.jdo.option.ConnectionUserName</name>
  <value>hive</value>
</property>
<property>
  <name>javax.jdo.option.ConnectionPassword</name>
  <value>hive</value>
</property>

When I use the below script:

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

I get the error below:

NotImplementedError: authMechanism is either not supported or not implemented.

Please help!

Please note that client will not allow me to upgrade the python version or to change the authentication mechanism in Hive.

Thanks in advance.

1) check this https://github.com/BradRuderman/pyhs2/blob/master/pyhs2/connections.py

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

authMechanisms should be one of these

2) Error on thrift.transport.TTransport.TTransportException: Could not connect to localhost:10000 Type netstat -a -n | grep 10000 netstat -a -n | grep 10000 and check service is listening on port 10000
