> This proposal talks about limitations of the YARN scheduling policies for SLA 
> applications, and tries to solve them by YARN-3806 and the new scheduling 
> policy called guaranteed capacity scheduling.
> Guaranteed capacity scheduling makes guarantee to the applications that they 
> can get resources under specified capacity cap in totally predictable manner. 
> The application can meet SLA more easily since it is self-contained in the 
> shared cluster - external uncertainties are eliminated.
