Hi,

I'm trying to output to elasticsearch using logstash and specifying hosts as environment variable is not working.

I see there's any issue as per this link [https://github.com/elastic/logstash/issues/6366](https://github.com/elastic/logstash/issues/6366)  
I'd like to know if there's an workaround

#declaring env. variable  
export HOSTS='["10.2.0.6","10.2.0.7","10.2.0.8"]'

# Sample logstash conf file to show how hosts is declared

input {  
}  
filter {  
}  
output {  
elasticsearch {

```
	hosts => ${HOSTS}

}	

```

}
