@bob human Problem seems to be at postgres. Can you please try to connect to postgres and check if you can query any table. #df -h #psql -U ambari ambari ambari>select * from host;

@Zhao Chaofeng Can you please show the /etc/ambari-server/conf/krb5JAASLogin.confconfig. You have executed setup-security to configure jass for ambari server? Please make sure that you have set complete keytab path while configuring. It should be something like below and verify the keytab and principal by doing kinit [root@hdp1 conf]# egrep "principal|keytab" /etc/ambari-server/conf/krb5JAASLogin.conf keyTab="/etc/security/keytabs/ambari.server.keytab" principal="ambari-server-hdp25@RAGHAV.COM" #kinit -kt /etc/security/keytabs/ambari.server.keytab ambari-server-hdp25

@Qi Wang I see that you have Impersonate enabled. Can you try with that option unset in interpreter config. Setting Impersonate will need passwordless ssh to be set between zeppelin user and the user who logs into zeppelin UI on your zeppelin host. Please try with Impersonate option unset in Livy interpreter.

@subash sharma No we dont have such feature to set policies as per Hive views. Ranger plugins are for the HDP services and are not related to Ambari views. If you would like to set authorization for views, you can set it from Ambari itself.

@prasad nuamatha Property tez.am.view-acls might be missing in tez-site.xml, please add "tez.am.view-acls" to custom tez-site and set the values to "*" (it can also be empty).
