Review request for Ambari, Alejandro Fernandez and Myroslav Papirkovskyy.


Bugs: AMBARI-9110
    https://issues.apache.org/jira/browse/AMBARI-9110


Repository: ambari


Description
-------

DataNode cannot start due to an Operation not permitted when trying to change the ulimit.
See screenshot.
Non-Root Setup:
 
# vipw 
root:x:0:0:root:/root:/sbin/nologin 

# echo > /etc/securetty 

# vi /etc/ssh/sshd_config 
PermitRootLogin no 
With that done I created a user named ‘ambari’ and used that during setup for the non-root
user to run the Ambari Server as. I’ve setup this in /etc/sudoers:
 
ambari	ALL=(ALL)	NOPASSWD: ALL 
I know this is best case for privileges, but want to get through one iteration before tightening
it up.
As well as this in /etc/sudoers.d/ambari (0440)
 
Defaults exempt_group = ambari 
Defaults !env_reset,env_delete-=PATH 
Defaults:ambari	!requiretty
