1. A method comprising: identifying high-availability jobs and low-availability jobs that demand usage of resources of a distributed system; determining a first quota of the resources available to low-availability jobs as a quantity of the resources available during normal operations; determining a second quota of the resources available to high-availability jobs as a quantity of the resources available during normal operations minus a quantity of the resources lost due to a tolerated event; executing the jobs on the resources of the distributed system; and constraining a total usage of the resources by both the high-availability jobs and the low-availability jobs to the quantity of the resources available during normal operations; and leaving jobs assigned to the lost resources without reassigning the jobs to reassigning resources; and reconstructing any unavailable data associated with the lost resources.
