My server is in a jelastic cloud. I installed elasticsearch in a Tomcat 7 + Maven 3 throw an war file following the tutorial disponible in Jelastic Blog.
Now the elasticsearch is and its up and running, but the tutorial I followed installed elasticsearch 0.19.3.
Now we are in 2.2.0.
How can I update to the newest version?
There are no clusters (I think), because I didn't make a test yet.
I'm really really new to this and just making tests in this platform. I need a very beginners guide.
