> 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
> 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.
