Issue in ElasticSearch Cluster

The first node you have to get running is es-master-01

Once you have ES running there and curl http://es-master-01:9200 gives you an ok response, then you can try to start the two other ones.

Before starting ES on the other VMs, make sure that curl http://es-master-01:9200 also works from them.

For es-master-01 I would use the IP for that VM in the curl commands.
