client hangs when connecting to HiveServer2

When I try to run the following code, the client hangs when trying to connect to Hive:

from impala.dbapi import connect

conn = connect(host='host_running_hs2_service', port=10000, user='awoolford', password='Bzzzzz')
cursor = conn.cursor()          <- hangs here
cursor.execute('show tables')
results = cursor.fetchall()
print results

I was able to connect to HiveServer2, via a Java client, and so it seems that the connectivity issue is Python/Impyla specific. When I debug/step-into, the code hangs at line 873 of hiveserver2.py.

Hive 1.1.0-cdh5.5.1 Python 2.7.11 | Anaconda 2.3.0 Impyla installed by pip today (2016-03-07).

Do you have any thoughts/suggestions?

@alexwoolford @wesm I was facing the same issue. Changing the auth_mechanism to ‘PLAIN’ worked for me. Here’s the documentation in the code: auth_mechanism : {'NOSASL', 'PLAIN', 'GSSAPI', 'LDAP'} Specify the authentication mechanism.'NOSASL’for unsecured Impala. 'PLAIN’for unsecured Hive (because Hive requires the SASL transport).'GSSAPI’for Kerberos and’LDAP’for Kerberos with LDAP. The default used is NOSASL: def connect(host='localhost', port=21050, database=None, timeout=None, use_ssl=False, ca_cert=None, auth_mechanism='NOSASL', user=None, password=None, kerberos_service_name='impala', use_ldap=None, ldap_user=None, ldap_password=None, use_kerberos=None, protocol=None):

@DVAlexHiggs Hi Alex, I also faced this issue. When I do fetchall() keep stopping without end or error.

I wonder if you solved this problem. Thanks!
