Hello,
We have upgraded our Elasticsearch component from v2.2.3 to v5.6.7. Post upgrade the elasticsearch process is not getting restarted.
We are not getting any elasticsearcglogs and it's failing to start. We are also using systemctl to start service.
and below is the status of systemctl
-bash-4.2$ sudo systemctl start elasticsearch
-bash-4.2$ sudo systemctl status elasticsearch
â elasticsearch.service - Elasticsearch
