I think I remembered my comment from last week- you may be able to combine
these into a single hosts/roles group by using the following construct:
```yaml
hosts: sensors
become: true
tags: sensors
roles:
-{ role: ambari_gather_facts, tags: [ 'always'] }
- { role: tap_interface, tags: ['tap'] }
- { role: pycapa, tags: ['pycapa'] }
- { role: bro, tags: ['bro'] }
- { role: flume, tags: ['snort','flume'] }
- { role: snort , tags: ['snort'] }
- { role: yaf, tags: ['yaf'] }
- { role: pcap_replay, tags: ['pcap-replay'] }
- { role: sensor-test-mode, tags: ['sensor-test-mode'] }
```
This is per the docs, so ymmv. But if it works as advertised, I think it's
a little bit more readable. Otherwise do what you got to do.
> Enable Each Component to be Installed Separately

> Key: METRON-180
> URL: https://issues.apache.org/jira/browse/METRON-180
> Project: Metron
> Issue Type: Improvement
> Reporter: David M. Lyle
> Labels: deployment
>
> To allow users of Metron to make the most use of the deployment scripts in
> highly-customized environments, a user should be able to choose whether each
> component is installed or not. This is currently possible in most cases, but
> there are a few scenarios that are not.
> For example, the PCAP service will only be installed if install_elasticsearch
> is set to "true". This was a good coupling back when PCAP searches were
> hosted in the index. Now that PCAP searches come from HDFS, we need to be
> able to install PCAP service separately.
