CLUSTERDOWN Hash slot not served in case of single master failure

website hash slot 在搭建版本的集群环境曾出现各节点无法互相发现与Hash槽分配异常CLUSTERDOWN Hash slot not served的情况，故而把解决方式记录下来。 hash slot Given a hashing table T with m slots, we want to store n = S keys, as maximum Important measure: load factor α = nm, the average number of keys per slot

hash slot Hash slots are defined by Redis so the data can be mapped to different nodes in the Redis cluster The number of slots can be  hash slot count Replica nodes will have a Master Slot Count of 0 Cluster Unassigned Slots Count: This is the number of slots which have not been assigned  Partition keys by slot-hash The resulting map honors order of the keys Type Parameters: K - Key type V -
