> - Implement more scale down policies (currently we have "NMs with least AMs" policy). Some ideas:
>     - Kill NMs with least number of MapReduce AMs (because MR has HA)
>     - Kill NMs with "most recently launched" AMs.
>     - Kill NMs with "certain labels" (With Hadoop v2.6 YARN supports Label Based Scheduling)
>     - Kill enough NMs to free up "X cpus, Y mem"
