连接时,Zookeeper java.net.NoRouteToHostException

这里为数据转储提前道歉.我有两台安装了Zookeeper的服务器.我想把它们作为一个整体来运行.这是我的zoo.cfg中的两个.

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/opt/zookeeper/data
server.1=solr1:2888:3888
server.2=solr2:2888:3888
clientPort=2181

两台服务器都有一个myid文件.它们的名字在/ etc/hosts文件中,所以它们绝对可以看到对方.当我使用zkServer.sh启动其中任何一个时,它表示zookeeper已启动.但是,当我运行"zkServer.sh status"时,我看到以下消息:

Using config: /opt/zookeeper/bin/../conf/zoo.cfg
Error contacting service. It is probably not running.

但是zookeeper java进程似乎正在运行,并且使用netstat显示tcp端口3888和2181正在侦听.当我尝试使用"sh zkCli.sh -server localhost:2181"连接到服务器时,我看到一堆环境信息,然后是一大堆这些日志条目:

2014-02-03 15:39:00,623 [myid:] - INFO [main-SendThread(localhost.localdomain:2181):ClientCnxn$SendThread@966] - Opening socket connection to server localhost.localdomain/127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error)
2014-02-03 15:39:00,646 [myid:] - INFO [main-SendThread(localhost.localdomain:2181):ClientCnxn$SendThread@849] - Socket            connection established to localhost.localdomain/127.0.0.1:2181, initiating session

2014-02-03 15:39:00,662 [myid:] - INFO  [main-SendThread(localhost.localdomain:2181):ClientCnxn$SendThread@1085] - Unable to read additional data from server sessionid 0x0, likely server has closed socket, closing socket connection and attempting reconnect

如果我尝试连接到其他服务器(sh zkCli.sh -server solr1:2181),我会看到一堆这样的:

2014-02-03 15:40:42,390 [myid:] - WARN  [main-SendThread(solr1:2181):ClientCnxn$SendThread@1089] - Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect
java.net.NoRouteToHostException: No route to host

Zookeeper似乎正在运行,尽管zkServer.sh状态另有说法.但有没有人对我的连接问题有任何见解？操作系统是RHEL 6.4,64位.
