Error: Could not find or load main class org.elasticsearch.tools.JavaVersionChecker


(Xceasar) #1

i tried to install elasticsearch 5.3 inside my docker, after adding a new user elsearch with following commands:
groupadd elsearch
useradd elsearch -g elsearch -p elasticsearch
chown -R elsearch:elsearch /root/elasticsearch-5.3.0/
su elsearch
cd /root/elasticsearch-5.3.0/bin/

and i tried to run elasticsearch:
./elasticsearch

i get error:
Error: Could not find or load main class org.elasticsearch.tools.JavaVersionChecker
Elasticsearch requires at least Java 8 but your Java version from /usr/bin/java does not meet this requirement

and i run java -version:
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

the system of docker is ubuntu 14.04

what's wrong... somebody help?

Hi,

I am not sure how your running Elasticsearch "inside your docker" is the right way. You should build a separate container. Refer to our documentation here:

https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html

From your docker container I would check:

sudo update-alternatives --config java

And see where /usr/bin/java points to. You may need to fix where /usr/bin/java points to, if it doesn't point to the same java version.


(Jason Tedor) #3

It's not clear to me how you've built your Docker image but all Elasticsearch distributions since 5.3.0 ship with a jar that contains org.elasticsearch.tools.JavaVersionChecker but it's clear that somehow you've lost that jar file. This is the root of your problem. Without more details, we can not help.


(Siva Prakash) #4

Same Jar file is working in MAC. but it is not working in Centos 7.
alternatives --config java

There are 3 programs which provide 'java'.

Selection Command

  • 1 java-1.8.0-openjdk.x86_64 (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.102-4.b14.el7.x86_64/jre/bin/java)

(Jason Tedor) #5

The problem might not appear be your Java version, the problem appears to be with your Elasticsearch installation first. Can you please list the contents of ../lib (from the directory where you were executing elasticsearch which you show as bin, go down one directory, and then into the lib directory. Please show the entire contents here.

Okay, the jar that we are looking for is there in both cases. Would you please run bash -x ./elasticsearch from the bin folder and share the results of the output here?

Okay, what does readlink -f /bin/java and /bin/java -version show?

(Jason Tedor) #12

I noticed this, this is in /root/; are you sure that you have the right permissions? I can reproduce your issue if I do this:

22:13:58 [jason@totoro:~/elasticsearch/elasticsearch-5.3.2/bin] $ chmod 000 ../lib
22:14:22 [jason@totoro:~/elasticsearch/elasticsearch-5.3.2/bin] $ ./elasticsearch
Error: Could not find or load main class org.elasticsearch.tools.JavaVersionChecker
Elasticsearch requires at least Java 8 but your Java version from /usr/java/latest/bin/java does not meet this requirement

You can not run Elasticsearch as root anyway, so let's get it out of the root folder and make sure you have the right permissions. I think the best way to make sure that you have the right permissions is to untar the tar archive again somewhere else.

:boom:


(Siva Prakash) #13

Thanks jasontedor. Its Working for me inside the VM...
but not able to access from the other system? do i need to change any IP Configurations?


(Jason Tedor) #14

You're welcome! You probably do, but for that we would need more details. Would you mind opening a new topic with more details of the problem and someone will take a look?
