Hello,
I try to access Hive from Spark in an Hadoop cluster where I use Ranger to
control Hive access.
As Ranger is installed, I have setup hive accordingly:
hive.security.authorization.manager=
org.apache.ranger.authorization.hive.authorizer.RangerHiveAuthorizerFactory
When I run Spark and I request it to access Hive table, it is using this
class to access it but I get several errors:
16/01/18 17:51:50 INFO provider.AuditProviderFactory: No v3 audit
configuration found. Trying v2 audit configurations
16/01/18 17:51:50 ERROR util.PolicyRefresher:
PolicyRefresher(serviceName=null): failed to refresh policies. Will
continue to use last known version of policies (-1)

And then (but it is not clear at all the two errors are connected) :
16/01/18 17:51:50 INFO ql.Driver: Starting task [Stage-0:DDL] in serial mode
16/01/18 17:51:50 ERROR authorizer.RangerHiveAuthorizer:

16/01/18 17:51:50 ERROR authorizer.RangerHiveAuthorizer:

And then the access to Hive tables fails.
I am not sure where to go from there. Any help would be appreciated.
Best Regards,
