Jian He commented on YARN-2986:
-------------------------------
Regarding the "policy-properties" take , I have one doubt that what if user
specify a policy-property outside of the "policy-properties" tag and
non-policy-property inside "policy-properties", will we throw exception or
ignore the settings? Ignoring seems confusing to users, as user may have no
idea which properties are set correctly and which properties are not. Either
way forces users to learn precisely which properties should be inside the
policy-properties tags and which ones should not. Each time a new property is
added, users also need to be learned. That's non-trivial effort to users.
