You can set your JVM settings before running the job to use different temp space, eg:

/tmp/sfd_batch_<uuid>

Scaffold has no built-in way to configure this, but if you are running from the command line, you might be able to do this with Python or bash:

export _JAVA_OPTIONS=-Djava.io.tmpdir=/new/tmp/dir
