Upgrading to OpenJDK 11 on customer-hosted instances

Looker supports OpenJDK version 11+ on customer-hosted Looker instances. This page describes how to upgrade from OpenJDK 8 to OpenJDK 11. Upgrading to OpenJDK 11 from OpenJDK 8 requires downloading and installing OpenJDK 11 and then downloading and installing a new looker startup script. For example:

1. Stop the Looker process from shell, as the lookeruser:

    sudo su - looker
   cd /home/looker/looker
   ./looker stop 
   

2. If you are updating a Looker cluster, repeat the previous step to stop Looker on every node.

3. Download and install OpenJDK 11 .

4. Download the looker11 startup script .

5. Delete the previous version of the looker startup script from your looker directory:

    rm looker 
   

6. Copy the looker11 startup script to your looker directory and rename the script looker . The new startup script must be called looker to run properly :

    mv <download_directory>/looker11 looker 
   

7. If you are updating a Looker cluster, repeat steps 3 through 6 on all nodes.

8. Start up Looker on all nodes.

    ./looker start
