Starting in Looker 22.2, Looker supports OpenJDK version 11 on customer-hosted Looker instances, which may improve Looker performance. 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:
Stop the Looker process from shell, as the looker user:
sudo su - looker cd /home/looker/looker ./looker stop
If you are updating a Looker cluster, repeat the previous step to stop Looker on every node.
Download and install OpenJDK 11.
Delete the previous version of the
lookerstartup script from your
looker11startup script to your
lookerdirectory and rename the script
looker. The new startup script must be called
lookerto run properly:
mv <download_directory>/looker11 looker
If you are updating a Looker cluster, repeat steps 3 through 6 on all nodes.
Start up Looker on all nodes.
