@yueyang

Pls try to add the below principal in your connection string, it 'may' help you

";principal=impala/hostname@REALM"

hostname - hostname where you have configured impala/hive

REALM - for your kerberos

Hi yueyang,

Can you please share your impyla source code and the error you are getting? That will help me understand why it failed.

Thanks
