hi @Shradha_Bharti - I saw this error on Elasticsearch 7.4.2 on CentOS 7. I realized that the problem was being caused because /etc/elasticsearch/elasticsearch.yml was missing on my system (I had accidentally checked it into RCS without checking it back out again). Upon replacing /etc/elasticsearch/elasticsearch.yml again, "systemctl start elasticsearch.service" worked properly again. Perhaps that will work for you - good luck
