Hello,
we set up a new cluster with RHEL 7
2 Data Nodes
3 Master Nodes
5 Shards
So we use elasticsearch-kopf
([https://github.com/lmenezes/elasticsearch-kopf](https://github.com/lmenezes/elasticsearch-kopf)), but it do not work.
elasticserach.log:
[2015-02-05 08:48:17,239][WARN][transport.netty]

I found out the problem is the different version in each elasticsearch node... Puting all the ES in the same version work fine...
Yo can see the version with the command:
> curl -XGET 'localhost:9200'
