Hiveserver2 + Kerberos + HTTP transport

[dignajar]

I'm trying to connect via Python3 to my Hiveserver2, running in the transport layer HTTP (port 10001), also I have Kerberos.

impyla==0.16a2

sasl==0.2.1
thrift_sasl==0.2.1
thriftpy==0.3.9
thriftpy2==0.4.0

from impala.dbapi import connect
conn = connect(host='<server>', port=10001,auth_mechanism='GSSAPI',kerberos_service_name='hive', use_http_transport=True)
cursor = conn.cursor()
cursor.execute('SHOW DATABASES;')
results = cursor.fetchall()
print(results)

Traceback (most recent call last):
  File "test.py", line 2, in <module>
    conn = connect(host='<server>', port=10001,auth_mechanism='GSSAPI',kerberos_service_name='hive', use_http_transport=True)
  File "/usr/local/lib/python3.6/site-packages/impala/dbapi.py", line 150, in connect
    http_path=http_path)
  File "/usr/local/lib/python3.6/site-packages/impala/hiveserver2.py", line 820, in connect
    transport.open()
  File "/usr/local/lib/python3.6/site-packages/thrift/transport/THttpClient.py", line 73, in open
    self.__http = http.client.HTTP(self.host, self.port)
AttributeError: module 'http.client' has no attribute 'HTTP'

Looks like the version from Github supports http as a transport layer.

@dignajar Looking at code, Kerberos authentication with HTTP Transport mode is not yet supported.
