Method Summary

Modifier and Type	Method and Description
void	onFailure(InetAddressAndPort from, RequestFailureReason reason) Called when there is an exception on the remote node or timeout happens
void	onResponse(Message<PaxosCleanupHistory> msg)
static PaxosStartPrepareCleanup	prepare(TableId tableId, java.util.Collection<InetAddressAndPort> endpoints, EndpointState localEpState, java.util.Collection<Range<Token>> ranges) We run paxos repair as part of topology changes, so we include the local endpoint state in the paxos repair prepare message to prevent racing with gossip dissemination and guarantee that every repair participant is aware of the pending ring change during repair.
