Abstract: The disclosed technology enables quicker initialization of a new master node for a cluster when a previous master node fails by tracking node state in the cluster prior to being designated the new master node. In a particular example, a method includes, in a first node, designated as a current master node for the cluster, managing the cluster based on states of the nodes determined by the first node. While the first node is designated the master node, the method includes each of the nodes collecting, and storing locally, the states of the nodes. In response to a failure of the first node, the method includes selecting a second node of the nodes a new master node. Upon being designated the new master node, the method includes the second node managing the cluster of nodes based on the states of the nodes that the second node collected and stored locally.
