Review comment:
So each time a compile query is run, it creates new source and new jar
files and that are added as resources. I was not certain at what point these
resources get distributed to the cluster, (is it when add jar is run or when
you create a function using the resource, or when you run a query using the
UDF). so I thought deleting on exit is safe enough because the permissions are
already very narrow on this jar.
