Jian He commented on YARN-1644:
-------------------------------

actually, if we change YARN-3867 to update the resource synchronously. Then, 
this race condition can be mostly avoided and RM can rely on the container 
status to recover the correct resource ?

> RM-NM protocol changes and NodeStatusUpdater implementation to support 
> container resizing
