Exception when installing S3 plugin

Elastic Stack Elasticsearch
1

I’ve received the following exception when trying to install the S3 plugin on one of the new nodes. I was able to install it on my older nodes and don’t recall running into this problem before.

  • OS: Ubuntu 18.04 LTS
  • JRE: openjdk-11-jre-headless
  • ES: 6.2.2
sudo bin/elasticsearch-plugin install repository-s3

This sounds like a broken java installation. I recommend you try purging the java package completely and reinstalling.

3

I just tried to install it on the second node that I have added today, and it gives the same error. Which JRE do you recommend that I install?

4

Just tried

sudo apt-get install default-jre

and tried installing the plugin again and am getting the same error.

Are you suggesting that I first run:

sudo apt-get purge openjdk-\*

and then reinstall?

5

Ok fixed. purged that JRE and installed Oracle JDK 10 and it is working fine now — thanks!

sudo add-apt-repository ppa:linuxuprising/java
sudo apt update
sudo apt install oracle-java10-installer
