I am trying to run elasticsearch after installation and getting the following error:

```

```

I checked everywhere and it looks like the problem is with the Java version.

I asked to upgrade the Java version, it was done, but still same error.

See below:

vpadmin@hbdchv016!:/var/log\> java -version  
`java version "1.8.0_31"`  
Java(TM) SE Runtime Environment (build 1.8.0\_31-b13)  
Java HotSpot(TM) 64-Bit Server VM (build 25.31-b07, mixed mode)

vpadmin@hbdchv016!:/var/log\> which java  
`/usr/java/jdk1.8.0_31_64/bin/java`

I also checked the PATH:

echo $PATH  
/app/oracle/product/12.1.0/dbhome\_1/bin`:/usr/java/jdk1.8.0_31_64/bin`:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/usr/local/bin:/usr/sbin:/local/bin:/tsanas/tsa/tooladm/scripts

This is the installation we use for new Java installations:

-rw-r--r--. 1 root root 326768640 Mar 1 11:01 jdk-8u31-linux-i586.tar  
-rw-r--r--. 1 root root 327393280 Mar 1 11:02 jdk-8u31-linux-x64.tar

Who can assist here pls?

Regards,  
Sharon.

Did you set `JAVA_HOME` or something?

FWIW this is a old version of Java8. You should upgrade.  
Yours is not supported: [https://www.elastic.co/support/matrix#show\_jvm](https://www.elastic.co/support/matrix#show_jvm)
