Remove the setting from your config file.

Yes if we remove setting, its working fine. But since then i have one more qwery regarding the below lines.
node.master: false
node.data: true
If we add the above 2lines, Elasticsearch service will start and immediately will be stopped.
So please let us know what configuration need to made change in elasticsearch.yml that need to send logs to other nodes also.

Probably because it can not find a master?
But it should not die.
Look at the logs and share them if needed

If you have 3 nodes, I'd recommend leaving default settings.
Have 3 master eligible nodes is what you want IMO.
