Provides a thrift_transport for use with hive connections with PyHive by defaulting to Pure-SASL.
PyHive relies on the sasl library for hive connections, but allows the user to optionally provide their own thrift_transport instead of relying on PyHive to create it. The main use case for this is Windows users where the sasl library is extremely difficult to compile from source.
The other use case for providing your own thrift_transport is to use other socket types, such as SSL.
The pure-transport has basic support for using SSL sockets in the thrift transport by passing use_ssl=True and optionally socket_kwargs.

When using a SQLAlchemy engine, it will automatically pass a port number of 10000 to the hive connection even if you explicitly do not put a port number in your connection string.
PyHive has an assertion that will not allow the keyword arguments [host, port, auth, kerberos_service_name, password] to have any other values besides None if a thrift_transport is specified. So using SQLAlchemy engine will raise a ValueError.
I see this assertion to be pointless, as providing any of these keywords will have no effect if a thift_transport is specified.
I recommend editing your hive.py file to comment out this part on lines 135-137 (as of version 0.6.1) if you want to use SQLAlchemy.
