US Patent 9594601 Planner for cluster management system

A processing device receives a starting cluster layout for a first cluster, a target cluster layout for the first cluster, and a cluster management operation for creating or modifying the first cluster. The processing device determines a plurality of node level tasks to transition the first cluster from the starting cluster layout to the target cluster layout, determines dependencies between the plurality of node level tasks, and determines an order for the plurality of node level tasks based on the cluster management operation and the dependencies. The processing device then creates an execution plan that divides the cluster management operation into the plurality of node level tasks in the determined order.
