ES2.2.0集群 Discovery和gateway设置

我的ES集群有10个节点，设置了3个master,10个data节点。
discovery设置
一个主节点的配置
network.host: 127.0.0..4
discovery.zen.ping.multicast.enabled: false//？2.2.0是否需要？
discovery.zen.ping.unicast.hosts:["127.0.0.3:9300","127.0.0.5:9300",,"127.0.0.31:9300","127.0.0.32:9300",
"127.0.0.33:9300","127.0.0.6:9300","127.0.0.7:9300","127.0.0.8:9300","127.0.0.9:9300"]
discovery.zen.minium_master_nodes:2
data节点：
discovery.zen.ping.unicast.hosts: ["127.0.0..4:9300","127.0.0..5:9300","127.0.0..3:9300"]

gateway设置：
gateway.recover_after_nodes: 8
gateway.recover_after_time: 5m

这样配置是否合适？有没有更好的配置？请各位不吝赐教！
