Elasticsearch throwing the exception: NoNodeAvailableException occured : No node available

Question

I\'m decided to try my first use for elasticsearch on a simple to-do list application. I followed this video to use the module and modified nothing in the module itself all

Answer 1

I had the same problem, what I did was:

1.Check if the nodes have the correct port open with:

telnet [ip address] 9300
Trying [ip address]
Connected to mynode1 ([ip address]).
Escape character is '^]'.
telnet> quit
Connection closed.    

2.Check that everything is ok with telnet =):

$ telnet [ip address] 9400
Trying [ip address]...
telnet: Unable to connect to remote host: Connection refused

3.Make sure you have the correct version of elasticsearch!

In the elasticsearch plugin that I'm using elastisearch 0.19.10 is used. When I installed elasticsearch on my server I accidentally used 0.20.1 which caused the: NoNodeAvailableException occured : No node available exception.

Hope this helps!
