Bikas Saha commented on YARN-289:
---------------------------------
Could it be that 2048 request got "reserved" onto that node and that prevented
the 1024 request from being assigned to that node?
> Fair scheduler doesn't satisfy smaller request when bigger one is outstanding

> An application requests a container with 1024 MB. It then requests a
> container with 2048 MB. A node shows up with 1024 MB available. Even if the
> application is the only one running, neither request will be scheduled on it.
