@Sam Red

The "Service 'userhome' check failed" is easy to resolve you need to create the home directory in

# su - hdfs 
$ hdfs dfs -mkdir /user/hive 
$ hdfs dfs -chown hive:hdfs /user/hive

Then retry the hive view.

That should work, let me know.

If Kerberos is enabled.Try the below steps:-

1)ambari-server setup-security

2)Enter choice, (1-5): 3

3)Enter ambari server's kerberos principal name ([email protected]): [email protected]

4)Enter keytab path for ambari server's kerberos principal:/etc/security/keytabs/ambari.server.keytab

5)Restart ambari server: ambari-server restart.
