title: How to import JSON file to ElasticSearch 6.x?
body: <p>I got a brand new empty installation of Elastic Search 6.1.1 running on port 9200 of my CentOS7 host. I have this "es.json" file with data sample ready to be inserted in the ES. </p>
  
  <p>I also have a log file in which each line is a json chunk. I could use both to populate my ES database.</p>
  
  <p>How do I insert this and other data to ES?</p>
  
  <p>I didnt find good explanations on the documentation and on the internet. for some reason the docs does not make it very clear</p>
