Description

Ambari 2.2.1.1 comes with the following upstart patch:
<https://issues.apache.org/jira/browse/AMBARI-14842>

This seems to break the Ambari upstart script in RHEL/CentOS6:

[root@slave-01 ~]# cat /etc/redhat-release
CentOS release 6.7 (Final)
[root@slave-01 ~]# rpm -qa|grep upstart
upstart-0.6.5-13.el6_5.3.x86_64
[root@slave-01 ~]# status ambari-agent
status: Unknown job: ambari-agent
[root@slave-01 ~]# ls -l /etc/init/ambari-agent.conf
-rwxr-xr-x 1 root root 1035 Mar 10 18:33 /etc/init/ambari-agent.conf

This is due to the following line present in /etc/init/ambari-agent.conf:
kill signal SIGKILL

Apparently, the upstart version shipped with RHEL6 doesn't support the kill
feature.

I'm not sure why this kill is required, as the ambari-server /etc/init/ambari-
server.conf doesn't contain it.

Can we have this kill line removed please? Or a separate /etc/init/ambari-
agent.conf file only for RHEL6 without this kill line?

IN ADDITION:

• the upstart script is deployed even on RHEL/CentOS7, where there is no upstart - it would be cleaner to only deploy the upstart script if upstart is actually installed on the system...
• request for systemd configs for both ambari-agent and ambari-server, since systemd is default in centos7
  A proposed patch is: <https://issues.apache.org/jira/browse/AMBARI-14526>
