Distributed cluster reconfiguration

A reconfiguration is distributed among multiple nodes of a cluster. Upon detecting an initiation of a reconfiguration of the cluster, reconfiguration functionality is delegated from the master node to one or more slave nodes in the cluster. Thus, multiple nodes perform reconfiguration functionality in parallel, such that one or more slave nodes perform delegated reconfiguration tasks that would conventionally be performed by the master node. The cluster reconfiguration can be in the form of one or more nodes joining or leaving the cluster. Data to facilitate the cluster reconfiguration can be transmitted from the master node to a slave node to which reconfiguration functionality is being delegated. Such data can include, for example, identifiers of nodes joining or leaving the cluster and/or information concerning the architecture and shared storage media of the cluster.
