Best practices in ES cluster tuning

I'm new in ES platform and want to know more. I've a 10 nodes hadoop cluster on HDP 2.6 and installed Elasticsearch on 1 node for test purposes.
I want to know if there are tutorials that explain how to tune both ES and hadoop platform's for best results. Are there any ebooks to?
Thank you.

Try the reference documentation and the webinars (you'll see them in the right hand column). In addition, there are various presentations, including from yours truly, available on the Internet from various conferences.

Thank you Costin

My pleasure. Hope it helps.
