> currently logged and non logged store ("job.logged.store.base.dir" and "job.non-logged.store.base.dir") return the same default values if not set. This is problematic because we always clean up non-logged store path when starting up, which would end up eliminating the logged store content as well and cause major data/state loss. The proposed fix here is:
> 1) logged and non logged store should pick different default values
> 2) we explicitly do a validation that these two configs are set to different; throw exceptions otherwise
> 3) update our config documentation about these two configs
