When rebuilding the index, 5.3.x will start throwing these warnings to a logfile <clustername>_deprecation.log;

Code: 
[2017-05-03T09:04:26,856][WARN ][o.e.d.r.RestController   ] Content type detection for rest requests is deprecated. Specify the content type using the [Content-Type] header.

Someone else encountering it: https://github.com/olivere/elastic/issues/511

https://www.elastic.co/guide/en/elasticsearch/reference/5.3/docs-bulk.html
When sending requests to this endpoint the Content-Type header should be set to application/x-ndjson.

I've caught this for XFES 1.1.7. We now send that content-type header whenever we request against the "_bulk" path.

(Talk about a misleading error message though, since we do pass a content type header through, just not the one they expect.)
