Getting:
[299 Elasticsearch-5.4.1-2cfe0df Content type detection for rest requests is deprecated. Specify the content type using the [Content-Type] header
This occurs are startup of FSCrawler.
Thought this was resolved with lastest:
Elasticsearch: 5.4.1
FSCrawler: 2.2
Any thoughts ?

This is fixed in FSCrawler 2.3. Try the latest SNAPSHOT. Link is available in the README.

TBH the latest 2.3-SNAP is more stable than the 2.2 version... 🙂
I hope I can release it anytime soon though.

Very interesting. Another user reported something like that. Ok can you open an issue in FSCrawler project. I'll check and fix that.
Thanks !
