---------------------------------------
I like the idea of a percentage; moves away from "number needed to be able to
do work" to "number needed to sustain the workload expected"
> Allow specification of minimum number of live containers for each component

> Issue Type: Task
> Reporter: Ted Yu

> While debugging a Slider-hbase deployment problem where client retrieved
> hbase-site.xml but verification of region server count failed, I found the
> following in SliderAppMaster log:
> {code}
> 2015-01-19 11:19:57,318 [AMRM Callback Handler Thread] INFO
> appmaster.SliderAppMaster (SliderAppMaster.java:onNodesUpdated(1603)) -

> health_report: "2/2 local-dirs are bad:
> /grid/0/yarn/local,/grid/1/yarn/local; 2/2 log- dirs are bad:

> In case there're not enough good nodes where requested number of components
> (such as region server) can be deployed, Slider shouldn't signal deployment
> success.
