What could be the reason behind .

[cdienger]

It looks like a libjli.so is missing. Try the following to verify/locate it:

Code: Select all

yum -y install mlocate
updatedb
locate libjli.so

What OS is this on? On my CentOS 7 install this file found under:

Code: Select all

/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.141-2.6.10.1.el7_3.x86_64/jre/lib/amd64/jli/libjli.so

What else has been installed on the server? The output would suggest that this is not a minimal install of the OS which is one of the requirements of. It is likely that something additional has caused conflict in the Java configuration.

Open /etc/java/java.conf with an editor like vi. It should have a line like:

Code: Select all

JVM_ROOT=/usr/lib/jvm

Try changing it to:

Code: Select all

JVM_ROOT=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.131-2.6.9.0.el7_3.x86_64

and then restarting the service:

Code: Select all

service elasticsearch restart

[radeshd28]

No change!

I see you have also opened an email ticket for this, so we will be locking this thread and continuing in the email ticket. In the future please only open one or the other so we are not duplicating our efforts.
