Hi @anelshaer, I assume you were following the RPM installation guide. Can you share more details about the commands you ran to get to this point, operating system and version, and Java version? It's definitely a Java problem, and if we can figure out what went wrong, we can get it into the troubleshooting section.

Same issue.
RPM installation, followed instructions exactly as written.
Java 1.8
CentOS 7.6.1810

Thanks @rlk5546. I'm able to reproduce and am looking into it with engineering. Looks to only be a problem on Java 8.

Hi everyone, our engineers tell me that those errors are nothing to worry about. If Elasticsearch fails to start, it's likely an incorrect symlink. I've added some information here: b4df35f

Thanks! It is refreshing to see such a quick response.

i get the following errors:
