About hinted handoff writes | DataStax Cassandra 2.0 Documentation

Hinted handoff is a Cassandra feature that optimizes the cluster consistency process and anti-entropy when a replica-owning node is not available, due to network issues or other problems, to accept a replica from a successful write operation. Hinted handoff is not a process that guarantees successful write operations, except when a client application uses a consistency level of ANY. You enable or disable hinted handoff in the cassandra.yaml file.
