redis 3.0 cluster ,client can not auto failover

[celesky]

redis version 3.2 and cluster is build with official solution
https://redis.io/topics/cluster-tutorial
i create the cluster:
master A and slave a
master B and slave b
master C and slave c

when my application started ,client will auto create connect with master node A,B,C.
but when i killed node A , client can not failover to a( a has upgrade to Master this time)
client will always send command to A node, but the problem is, node A is down.

it should auto update the cluster infomation, and auto reconnect to the new master node a.
