Masternotdiscoveredexception elasticsearch

Sometimes, when you want to join a node to  elasticsearch cluster, this problem may occur (the reason may vary, but I think there are some limitations of using multicast here)

Uncomment those lines in elasticsearch.yml

We tell this host (node) to use unicast discovery instead of multicast, and then specify the master host manually for this node.
