This is expected behavior and nothing to be concerned about.

Curator performs a `GET` with a dummy index name in order to get date math calculations from Elasticsearch, rather than attempting to do the date math calculations in Curator.

Because you are in `DEBUG` logging, you see it happen. Otherwise you never would have known.
