ElasticSearch 7.x not working after upgrade

In case you have upgraded elastic search by mistake and want to rollback to the previous working version, here are the steps. In my case, I upgraded the ElasticSearch to 7.9.2-1 and wanted to rollback to 7.6.2-1 1. yum downgrade elasticsearch-7.6.2-1 2. Restart elasticsearch sudo service elasticsearch start I hope it will work but in case you are facing any of the following issues, please run respective comments. Errors: Problem . Unable to create temporary keystore at [/etc/elasticsearch/elasticsearch.keystore.tmp] Solution : sudo -u elasticsearch -s /usr/share/elasticsearch/bin/elasticsearch-keystore create Problem : Likely root cause: java.nio.file.AccessDeniedException: /etc/elasticsearch Solution : chmod g+w /etc/elasticsearch Thanks!!
