Hello, As you can notice , I am trying the work done on this new release. preload-files and preload-binary options are very interesting to me because I work on a cluster without any shared space between nodes. I tried those basically , but no success . You will find below the error messages. If I did things wrong, would it be possible to get simple examples showing how these options work.
