Error when Connecting Load Balancer with Impyla

New Contributor

I am using python shell to connect to with impala with Cloudera Impyla (github.com/cloudera/impyla)

 

 

After I am using kinit command, I start to connect inside python session with following command and get the following error. Please advice. Thanks

 

 

from impala.dbapi import connect

con = connect(host=<IMPALA_LOAD_BALANCER_NODE>, port=25003, auth_mechanism="GSSAPI", use_ssl=True).cursor()

TApplicationException: Invalid method name: 'OpenSession'
