I stopped ES service, then used:
sudo yum remove elasticsearch
To get it out of here. I changed repos files to use 6.x versions.
Then i tried installing it with
sudo yum install elasticsearch-6.7.2
But i get this error:
could not find java; set JAVA_HOME
error: %pre(elasticsearch-0:6.7.2-1.noarch) scriptlet failed, exit status 1
Error in PREIN scriptlet in rpm package elasticsearch-6.7.2-1.noarch
