Daniel Templeton commented on YARN-6453:
----------------------------------------

LGTM.  Can you also please add a statement into the fair scheduler docs so that admins know
about this?

> An empty fairscheduler-statedump.log is getting generated despite fair share not being
the configured scheduler and for every service.  i.e., starting a namenode will also generate
this file.  For single node test installations, this is a major problem if the services are
started as different users and/or with secure daemons.
