我正在尝试在AWS上设置zookeeper群集，并且在运行zookeeper时遇到以下错误：
[2017-03-22 11:32:25,038] INFO Notification time out: 1600 (org.apache.zookeeper.server.quorum.FastLeaderElection)
[2017-03-22 11:32:31,644] WARN Cannot open channel to 2 at election address /<IP2>:3888 (org.apache.zookeeper.server.quorum.QuorumCnxManager)

知道怎么解决吗??
我的zookeeper.properties是这样的：
dataDir=/tmp/zookeeper
# the port at which the clients will connect
#clientPort=2181
clientPort=2080
# disable the per-ip limit on the number of connections since this is a non-production config
maxClientCnxns=0
server.1=0.0.0.0:2888:3888
server.2=<IP2>:2888:3888
#add here more servers if you want
initLimit=5
syncLimit=2
tickTime=2000
我的猜测：我认为存在一些网络问题。但我不知道该怎么办？
