Install jar file in Compute libraries

Upload a jar file (e.g. driver file) and install it

Click into the Compute

Go to the Libraries tab

Click Install New

There multiple source options, e.g. PyPI, S3, Volumes, Workspace, etc.

One way to install Jar file is using the Volumes, which is a storage attached to a Catalog.

Firstly create the volume in the Catalog

From the New on the top left in the menu bar, 

Select Upload files to volume

Browse to the Catalog and the schema, e.g. the default schema of your prod catalog

Expand the schema and it will show the volumes attached to that schema

Click Create a volume to create a new one, e.g. drivers

Then it has the option to upload files to the created volume.

upload the Jar file to the volume

When done, go back to the Compute's libraries and install new

Choose volume as the source, browse to the volume where the JAR file is uploaded to, 

Then select the jar file and install.

In older version of databricks, it has to use File Path/S3 to specify the driver file's path in the volume

If the jar file will be shared with other Compute clusters,

the jar needs to be added to the allow list

Click on Catalog in the left menu bar, click the 'Gear' the configuration icon

Go to the Allowed JARS tab

Put in the uploaded jar file's full path in the volume
