+1 (non-binding) works fine, and a much needed fix as well ! If for some
reason, we were not able to install the templates during the startup, it would
be caught by the service check.
Validated this on a full dev environment. For a successful service check, I
see this now:
```
2017-11-10 15:48:06,150 - Checking Elasticsearch templates for Indexing
2017-11-10 15:48:06,151 - Execute['curl -s -XGET
"http://node1:9200/_template/yaf_index"; | grep -o yaf_index'] {'logoutput':
True, 'path': ['/usr/sbin:/sbin:/usr/local/bin:/bin:/usr/bin'], 'tries': 3,
'user': 'metron', 'try_sleep': 5}
yaf_index
yaf_index
2017-11-10 15:48:06,343 - Execute['curl -s -XGET
"http://node1:9200/_template/error_index"; | grep -o error_index'] {'logoutput':
True, 'path': ['/usr/sbin:/sbin:/usr/local/bin:/bin:/usr/bin'], 'tries': 3,
'user': 'metron', 'try_sleep': 5}
error_index
error_index
2017-11-10 15:48:06,385 - Execute['curl -s -XGET
"http://node1:9200/_template/snort_index"; | grep -o snort_index'] {'logoutput':
True, 'path': ['/usr/sbin:/sbin:/usr/local/bin:/bin:/usr/bin'], 'tries': 3,
'user': 'metron', 'try_sleep': 5}
snort_index
snort_index
2017-11-10 15:48:06,433 - Execute['curl -s -XGET
"http://node1:9200/_template/bro_index"; | grep -o bro_index'] {'logoutput':
True, 'path': ['/usr/sbin:/sbin:/usr/local/bin:/bin:/usr/bin'], 'tries': 3,
'user': 'metron', 'try_sleep': 5}
bro_index
bro_index
2017-11-10 15:48:06,491 - Execute['curl -s -XGET
"http://node1:9200/_template/metaalert_index"; | grep -o metaalert_index']
{'logoutput': True, 'path': ['/usr/sbin:/sbin:/usr/local/bin:/bin:/usr/bin'],
'tries': 3, 'user': 'metron', 'try_sleep': 5}
metaalert_index
```
And the service check fails when I delete the ES template file.
```

@nickwallen - I see two conflicting files for the commit. Guess this would
be need to be resolved first?
> Service Check Should Check Elasticsearch Index Templates
> --------------------------------------------------------
>
> Key: METRON-1311
> URL: https://issues.apache.org/jira/browse/METRON-1311
> Project: Metron
> Issue Type: Bug
> Affects Versions: 0.4.1
> Reporter: Nick Allen
> Assignee: Nick Allen
> Fix For: Next + 1
>
>
> The Service Check in Ambari does not validate that the Elasticsearch index
> templates have been installed. Without these index templates bad things can
> happen. For example, the Alerts UI will not be able to display any alerts.
> The Elasticsearch index templates that are installed by Ambari should also be
> checked as part of the Metron Service Check.
