Hi,

I wanted to know if there have been any changes to the Logstash configuration process from the previous versions. I created a mapping in ES 6.0 and wanted to send data to it using Logstash. So, my pipeline was as follows:

File -\> Logstash -\> Elasticsearch

However, when I try to run my Logstash config file, it prints the following message to Powershell console:

```

```

My Elasticsearch instance is running absolutely fine but the error says that the instance is dead.

The error message indicates that ES requires you to authenticate yet Logstash hasn't been configured to supply any credentials.
