------------------------------------
Summary: ambari-server not running when (re)started via ansible
'command' or 'shell' module
Key: AMBARI-9215
URL: https://issues.apache.org/jira/browse/AMBARI-9215
Project: Ambari
Issue Type: Bug
Affects Versions: 1.6.1
Environment: HDP 2.1 on RHEL 6 with 2.1.GlusterFS stack.
Reporter: Daniel Horak
When I start ambari-server via ansible 'command' or 'shell' module, ambari
server immediately stop, when the ansible command finish.
*How to reproduce:*
1) prepare ansible inventory file (you have to have configured passwordless ssh
to the server AMBARI.EXAMPLE.COM).
{noformat}
# echo "AMBARI.EXAMPLE.COM" > hosts
{noformat}
2) check ansible configuration
{noformat}
# ansible AMBARI.EXAMPLE.COM -i hosts -m ping
AMBARI.EXAMPLE.COM | success >> {
"changed": false,
"ping": "pong"
}
{noformat}
3) run ambari-server restart (and sleep 30) via ansible and in the meantime,
check the state of ambari-server on the server AMBARI.EXAMPLE.COM.
{noformat}
# ansible AMBARI.EXAMPLE.COM -i hosts -m shell -a "ambari-server restart; sleep
30"
AMBARI.EXAMPLE.COM | success | rc=0 >>

{noformat}
*Note:* when I use ansible 'service' module, it works well, but I need to use
'shell' module, because it is called from longer shell script (direct call
{{ambari-server restart}} is just reproducer). Also restarting other services
this way (e.g. ambari-agent) works well.
