Redis version is 3.2.8 and running in an inner net environment Recently, I found one or more slave lost connection to master with a message "master_host: ?" in INFO REPLICATION. However, when I use CLUSTER NODES, I found the master node exists and master-slave relation is correct.
so my question is 1) in which situation could this happened 2) is there some parameter to control the slave reconnecting to master with the info of CLUSTER NODES this slave holds
