Elasticsearch does not start without any logs

I am having trouble starting elasticsearch. I had to restart my amazon ===
instance running ES 5.5. This is what I see.

systemctl status elasticsearch

service failed.

1. No log files have been created in /var/log/elasticsearch

2. I have tried increasing the heap size but that has not helped

3. I have reinstalled ES and that has not helped.

Anything else I should try.

thanks

Hi @rpazhyannur
Did you do any configuration or update before restarting elasticsearch ? I had similar problem while upgrading elasticsearch from 5.4 to 6.0 Elasticsearch Service won't start after full cluster upgrade from 5.4 to 6.0. It was related to the start up script
