使用 pyhive 和 pyodbc 从 Windows 连接到 hive

Question

Hi I want to connect to hive using python libraries pyhive and pyodbc:

     conn = hive.Connection(host="hostname",port=10001,username="********",database="default",auth='KERBEROS',kerberos_service_name="hive")

the error I am getting

     TTransportException: Could not start SASL: b'Error in sasl_client_start (-4) SASL(-4): no mechanism available: Unable to find a callback: 2'

And When I am using pyodbc then

conn_string="""DSN=%s; Host=%s, Port=%d, Database=default; AuthMech=3;UseSASL=1; UID=%s; PWD=%s; SSL=1;AllowSelfSignedServerCert=1"""% (cfg['DSN'], cfg['host'], cfg['port'],cfg['username'], cfg['password'])

conn = pyodbc.connect(conn_string, autocommit=True)

This is the error I am getting so Please if anyone who has been successful in connecting python with hive by pyodbc, pyhive Please Help

Hive is hosted in Cloudera.

Answer 1

pyhive needs sasl dependencies

on linux install by yum/apt

on windows after install package cyrus-sasl, need to configure sasl2 directory
located site-packages/sasl or Library/bin/

method 1: copy sasl2 folder to C:\\CMU\\bin\\

method 2: add registry string

HKEY_LOCAL_MACHINE\SOFTWARE\Carnegie Mellon\Project Cyrus\SASL Library\SearchPath
C:\Users\cdarling\Miniconda3\envs\hive\Library\bin\sasl2
