Hi,

Can you give:
OS and ES version ?

Can you past the result of:

more /var/log/elasticsearch/<clustername>.log

There is probably more informations in the full log.

Your JAVA_HOME is probably incorrectly set. Check it.

hi,

It is pretty strange that there is no log into the directory when you start the service...
Without the full trace, it will be easier to find a solution.

@KKB

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/elasticsearch/bootstrap/Elasticsearch : Unsupported major.minor version 52.0

are you certain that this version is used to start elasticsearch ? Try :

java -version
