My Configuration file screenshot

My Configuration file is in text format:-
cluster.name: verdantis
node.name: DATA-${}
node.data: true
node.master: true
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
#path.repo: ["/home/data_ElasticSearchBackup"]
bootstrap.memory_lock: true
bootstrap.seccomp: false
transport.tcp.port: 9300
discovery.zen.ping.unicast.hosts: ["","",""]

Please don't post pictures of text, they are difficult to read and some people may not be even able to see them.

Please check your Elasticsearch logs as well.

Thanks for your time and answer. I am new to Elasticsearch and centOS. Could you please let me know what is wrong in my configuration file(I have added my configuration file in text format) and reason for failure of Elasticsearch start.
