Ok, I seem to have hive up and running with mysql, but now I cannot get ranger admin to start:

I created the database and user accounts in mysql it needs, but I don't see why it would give a "permission denied" error attempting to stop ranger-admin. I tried running the script manually from the root account, to no avail.

The below statement is wrong though it runn successfully. Notice the .* after rangerdb

mysql> GRANT ALL PRIVILEGES ON rangerdb.* TO 'ranger'@'nn.example.com' IDENTIFIED BY 'rangerdba';

The below statement should be run 

mysql> GRANT ALL PRIVILEGES ON rangerdb TO 'ranger'@'nn.example.com' IDENTIFIED BY 'rangerdba';

Then retry

Could you provide us the output from the ls -la command for /usr/bin/ranger-admin-stop?

@Gary Cameron

Whats the output of below command

# hostname -f

From MySQL prompt 

Mysql>show grants;

Then run this grants statement after connect like root

mysql> use rangerdb;
mysql> GRANT ALL PRIVILEGES ON * . * TO 'rangerdb'@'%'; 
mysql> Flush privileges;
mysql> quit;

And retry it looks a privilege issue

Wow, more circular symlinks! I'm not sure how my ranger install got itself so borked.

@Gary Cameron

You can restart your Ranger setup with the attached a customized document. You will need to ensure you are ROOT when creating the user ranger or whatever user with corresponding password of your choice. Then log on as ranger to create the ranger database then exit and continue through the Ambari UI you should be fine.

Happy Hadooping

Sorry about the spam, made it a bit further on my own:

mysql> GRANT ALL PRIVILEGES ON rangerdb.* TO ranger@nn.example.com IDENTIFIED BY 'rangerdba';
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-nn.example.com IDENTIFIED BY 'rangerdba'' at line 1 
mysql> GRANT ALL PRIVILEGES ON rangerdb.* TO 'ranger'@'nn.example.com' IDENTIFIED BY 'rangerdba';

Query OK, 0 rows affected (0.00 sec)

It now only fails to start the last component:

Ok, I compared with another system and manually fixed the symlink:

[root@bu-hdp2-nn ranger-admin]# ln -s /etc/ranger-admin/2.4.2.0-258/0 conf 
[root@bu-hdp2-nn ranger-admin]# ls -l conf
lrwxrwxrwx. 1 root root 31 Oct 27 15:36 conf -> /etc/ranger-admin/2.4.2.0-258/0

Now when I restart the error is different:
