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.
Download the
looker11
startup script.Delete the previous version of the
looker
startup script from yourlooker
directory:rm looker
Copy the
looker11
startup script to yourlooker
directory and rename the scriptlooker
. The new startup script must be calledlooker
to 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.
./looker start
