我有两个zookeeper / kafka服务器。 比方说，
10.10.1.9
10.10.1.10
当我使用配置启动我的zokeeper时：
在10.10.1.9，
dataDir=/var/zookeeper
# the port at which the clients will connect
clientPort=2181
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=0
initLimit=5
syncLimit=2
server.1=10.10.1.9:2888:3888
server.2=10.10.1.10:2888:3888
我在10.10.1.9上收到以下警告：
[2016-05-23 07:26:56,047] WARN Cannot open channel to 2 at election address /10.10.1.10:3888 (org.apache.zookeeper.server.quorum.QuorumCnxManager)

意思是说zookeeper无法连接到10.10.1.10服务器。
ON 10.10.1.10 zookeeper日志，我得到以下日志：

有人遇到过这样的问题吗？任何的想法？ 您是否可以列出所有端口权限或要为两个zookeeper服务器进行通信而做的任何其他事情。
先谢谢你们!!
