Description

common-services/SPARK/1.2.1/package/scripts/service_check.py:36

 livy_kinit_cmd = format("{kinit_path_local} -kt {smoke_user_keytab} {smokeuser_principal}; ")
 Execute(livy_kinit_cmd, user=params.livy_user)

Notice the Kerberos identity is for the smoke user, but the exec is for the livy user. This will replace the livy user's interactive Kerberos ticket cache.

This should be 

smoke_user_kinit_cmd = format("{kinit_path_local} -kt {smoke_user_keytab} {smokeuser_principal}; ")
Execute(smoke_user_kinit_cmd, user=params.smoke_user)

Where smoke_user is

smoke_user =  config['configurations']['cluster-env']['smokeuser']
