From a pure feature perspective, I think it makes sense to support this for non-yarn modes as well. While Facebook uses a custom scheduler, we rely on this leveldb state to be robust against external shuffle service failures/restarts (for certain deployment types). Although admittedly, I lack full context behind as to why this was only done for Yarn to begin with. cc @dafrista @squito who might've more details there.
