Tried to enable HTTP CORS on ES, but after I added  
http.cors.enabled: true  
http.cors.allow-origin: "\*"  
to elasticsearch.yml, ES can't start and I got this error:

```

Looks like your configuration file isn't valid YAML. Pay attention to the indentation. If you post the configuration file here we can help you debug it, but make sure you format it as code using the toolbar button.

Here's the problem:

```auto
...
# Set a custom port for HTTP:
#
# http.port: 9200
  http.cors.enabled: true
  http.cors.allow-origin: "*"
#
...

```

Don't indent the http.cors.\* lines.

# Set a custom port for HTTP:
#
# http.port: 9200
http.cors.enabled: true
http.cors.allow-origin: "*"
#
...

```

Yes, exactly. No whitespace at the beginning of the line.
