Hitesh Shah commented on TEZ-2687:
----------------------------------
The RM kills the AM as soon as it unregisters so this might end up causing less
data to be published to timeline if the scheduler service stops before the
history service.
> ATS History shutdown happens before the min-held containers are released
> ------------------------------------------------------------------------
