SUCCESS: Integrated in Hadoop-Hdfs-trunk #1792 (See 
[https://builds.apache.org/job/Hadoop-Hdfs-trunk/1792/])
YARN-2022 Preempting an Application Master container can be kept as least 
priority when multiple applications are marked for preemption by 
ProportionalCapacityPreemptionPolicy (Sunil G via mayank) (mayank:

> Cluster Size = 16GB [2NM's]
> Queue A Capacity = 50%
> Queue B Capacity = 50%
> Consider there are 3 applications running in Queue A which has taken the full 
> cluster capacity. 
> J1 = 2GB AM + 1GB * 4 Maps
> J2 = 2GB AM + 1GB * 4 Maps
> J3 = 2GB AM + 1GB * 2 Maps
> Another Job J4 is submitted in Queue B [J4 needs a 2GB AM + 1GB * 2 Maps ].
> Currently in this scenario, Jobs J3 will get killed including its AM.
> It is better if AM can be given least priority among multiple applications. 
> In this same scenario, map tasks from J3 and J2 can be preempted.
> Later when cluster is free, maps can be allocated to these Jobs.
