Wangda Tan commented on MAPREDUCE-6304:
---------------------------------------
Just found I'm not in the watcher list, missed some discussions.
I think [~john.jian.fang]'s use case is very unique but also interesting,
platform provider has no control and knowledge of user's applications, and user
doesn't understand about platform's details such as which machine is temporary
or not.
Maybe a possible way to solve this problem is to add a
global-am-resource-request setting, which can include node-label-expression,
node/rack information. Because as YARN RM, it doesn't know what's the
application's running model, it only knows which container is AM or not, which
seems enough for your requirements.
But adding such global-am-resource-request setting can also be dangerous, such
as how about a queue is not accessible node-label-expression of
global-am-resource-request?
