Description

Currently, if a mutable request (POST, PUT, DELETED) is issued to a cluster, the request is replicated and if any node fails to perform the request, it is disconnected (unless all nodes fail, in which case no node is disconnected). However, often times, the failure is due to some sort of socket timeout. As a result, we should request that the node re-join the cluster, as long as its flow matches the cluster's flow.
