The special case of Starting allowed us to make sure every node in a cluster waited for the whole cluster to come up, but caused problems later if a node died and came back. We drop the Starting state for clusters, treating a STARTING node as equivalent to an UNKNOWN (or DOWN) node for purposes of cluster state, so clusters will go from Down to Degraded to Normal as nodes come up. We now wait for the Normal state during initial bringup. We would previously have accepted Degraded, if you could reach it, for instance if a node came up and then went down again before another node finished starting, but I'm pretty sure that was unintentional. This solves a problem where while a node was down, we'd accept queries that we could handle in a degraded state, but then we'd *stop* accepting them when the node started coming back up. |
