Hi,

looking at the following lines in lines:
[2017-09-04T17:14:07,704][INFO ][o.e.d.z.ZenDiscovery ] [es55] failed to send join request to master [{es54}{EfAxONJ2RaOWELG_yGZNxg}{fW43Cr6bSay8m5B7CRJl2g}{192.168.3.54}{192.168.3.54:9300}], reason [RemoteTransportException[[es54][192.168.3.54:9300][internal:discovery/zen/join]]; nested: NotMasterException[Node [{es54}{EfAxONJ2RaOWELG_yGZNxg}{fW43Cr6bSay8m5B7CRJl2g

there is problem with es54 node. unable to connect with 192.168.3.54:9300 node. Check 9300 port is in firewall or not?
command for checking it: firewall-cmd --list-ports
if port is not add then add it in the firewall.
for making cluster , 9200 and 9300 both port should be open for communications between nodes.
Also there should be entries of both nodes in /etc/hosts file.
