Hi @Shelton Finally I've solved the problem and hope my experience could help someone else who is banging his/her head on this scenario. At time of writing I was accessing the GCP cluster via public IP addresses. I had a /etc/hosts file resolving hostnames to their public IP Then customer's NOC granted me access from internal network over VPN and next attempt went fine. Still can't understand why, maybe some networking related config issue, but being on the internal side of the network solved my problem Simple as that! Thanks for your precious support, and patience Stefano

@Lewis @Shelton @Prakashcit Hi All, I did ranger re-installation and now it is working, but if i integrate hive with ldap, again getting same null pointer exception. Note: we integrated hive with ldap not ranger, just creating same ldap user in ranger (local) and trying to match it with LDAP user. whether it will create any problem? Kindly advice on this. select * from asop.test; Error: Error while compiling statement: FAILED: NullPointerException null (state=42000,code=40000)

@kirkade Unfortunately I have MySQL databases but if you could conserve that instalment I could try to reproduce your problem this weekend. I have been overloaded these past days ....To my experience reinstallation might not resolve the problem its usually a good learning curve to face a problem head one just imagine ypu were at a client site you wouldn't ask them to reinstall the environment. Just share the create and postgres load scripts and version so I can reproduce your problem.

@Shelton @EricL Thank you both. the correct ACL spec is group::r-x Now the following command works. sudo -u zeppelin hadoop fs -ls /warehouse/tablespace/managed/hive/test1 From what I just ran into, I feel that, by design, Hive takes extra effort to prevent users from accessing managed table files directly. I will follow that design and access Hive managed table only through Hive.

Sorry for the bump. I tried this in the HDP Sandbox and discovered that installing krb5-workstation-1.15.1-37.el7_7.2.x86_64.rpm solved the problem

@peterpiller I think you will need to setup cross-realm trust between two MIT KDC for REALM_01 and REALM_02 if you have a mix of MIT KDC and AD then have a look at this MIT/AD Kerberos setup this will ensure you have a valid ticket for both domains. HTH

@mike_bronson7 When your cluster is in HA it uses a namespace that acts as a load balancer to facilitate the switch from active to standby and vice versa. The dfs-site-xml holds these values filter using dfs.nameservices the nameservice-id should be your namespace or in HA look for dfs.ha.namenodes.[nameservice ID] dfs.ha.namenodes.[nameservice ID] e.g dfs.ha.namenodes.mycluster And that's the value to set eg hdfs://mycluster_namespace/user/ams/hbase The refresh the stale configs , now HBase should sending the metrics to that directory HTH
