Hello,

There is a few things I can see from this output.

```auto
2017-11-23T12:43:12Z CRIT Exiting: Could not start registrar: Error loading state: Error decoding states: json: cannot unmarshal object into Go value of type []file.State

```

I think there is either a problem with the content of the registrar or a permission issue and the error is hidden somehow. Can you add to this issue the output of the following command:

```auto
 cat /var/lib/filebeat/registry

```

Also, I haven't tried it. But I believe AWS Elasticsearch **always requires signing request?** , but Filebeat currently doesn't support that.

There is a few related discussion here:

Thanks
