Hi All,

I am trying to get the [netflow codec](https://www.elastic.co/guide/en/logstash/master/plugins-codecs-netflow.html#plugins-codecs-netflow) work with multiple definition files.  
I understand that "netflow\_definitions" configuration option is a valid file system path.  
However, when I try to configure this path as a directory and include multiple netflow definition yaml files, logstash errors out with the following error:

```auto
:exception=>"RuntimeError", :message=>"LogStash::Codecs::Netflow: Bad syntax in definitions file /usr/share/logstash/pipeline/elastiflow/definitions", :backtrace=>["/usr/share/logstash/vendor/bundle/jruby/2.5.0/gems/logstash-codec-netflow-4.2.1/lib/logstash/codecs/netflow.rb:382:in load_definitions'",

```
