ElasticSearch StartUp Error

Hi All,

I have Elasticsearch installed on RedHat machine.
I get the below error when i run the start command:
elasticsearch.service - Elasticsearch
Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; disabled; vendor preset: disabled)
Active: failed (Result: exit-code) since Tue 2016-10-25 06:45:00 EDT; 1h 21min ago

Please advice.

I would suggest looking at your elasticsearch log and /var/log/messages or journalctl
