The increasing diversity of frameworks and workloads that run atop a Hadoop cluster gives more flexibility and power to users, but make it very difficult for an administrator to ensure that SLAs are met while allowing exploratory, ad-hoc usage to continue to use all spare capacity. We present our vision and implementation for generalised resource management on Hadoop, suitable for all uses.
