Big Data Connector Hive with Kerberos problem

HEllo,

Trying Knime Analytics Platforme With Big Data Trial Connectors, i try to configure the Hive Connectors and after adding my :

hostname,port,databasename; i added my parameter as principal=principalname/localhost@MYREALM.CORP

Authentification : Use Kerberos.

I try to execute and get this error :

WARN Hive Connector 2:1 failed to apply settings: Database connection could not be validated: Cannot locate default realm
ERROR Hive Connector 2:1 Exception creating Kerberos based Hive connection: Can't get Kerberos realm

Can you help me ?

Thx.

Regards.

Hi Renaud,

for Kerberos, Cloudera's proprietary drivers still require some connection parameters.

For impala (replace XXX with the fully qualified domain name of the
impala host):
AuthMech=1;KrbRealm=YOUR.REALM;KrbHostFQDN=XXX;KrbServiceName=impala

and analogous for Hive (replace XXX with the fully qualified domain
name of the Hiveserver2 host):

AuthMech=1;KrbRealm=YOUR.REALM;KrbHostFQDN=XXX;KrbServiceName=hive

These options are also described in more detail in the PDFs that come
with the drivers.

Best,
Björn
