Review request for Ambari and Vitalyi Brodetskyi.


Bugs: AMBARI-11912
    https://issues.apache.org/jira/browse/AMBARI-11912


Repository: ambari


Description
-------

After installation Ambari is removing the default `ranger` group from `ranger`
user and adding the `hadoop` user. This is breaking Unix Authentication.

Before Installing Ranger through Ambari

    
    
    [root@pa-0105-postgres-1 yum.repos.d]# cat /etc/passwd | grep ranger
    [root@pa-0105-postgres-1 yum.repos.d]# yum install -y ranger-admin
    [root@pa-0105-postgres-1 yum.repos.d]# cat /etc/passwd | grep ranger
    ranger:x:2546:498:Ranger:/var/lib/ranger:/bin/bash
    [root@pa-0105-postgres-1 yum.repos.d]# groups ranger
    ranger : ranger
    [root@pa-0105-postgres-1 yum.repos.d]# yum install ranger-usersync
    [root@pa-0105-postgres-1 yum.repos.d]# ls -l /usr/hdp/current/ranger-usersync/native/
    total 8
    -rwsr-x---. 1 root ranger 5640 Jun  1 00:13 credValidator.uexe
    

After Installing Ranger through Ambari

    
    
    [root@pa-0105-postgres-1 ranger-usersync]# groups ranger
    ranger : hadoop
