问题如下：
在启动namesrv、 broker后，创建Topic一直出现如下的问题，没有找到解决方法
[root@localhost bin]# sh mqadmin updateTopic ‐c DEFAULT_CLUSTER ‐n 192.168.202.128:9876 ‐t TopicTest1 ‐r 10 ‐w 10
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0
usage: mqadmin updateTopic [-b ] [-c ] [-h] [-n ] [-o ] [-p ] [-r ] [-s ]
-t [-u ] [-w ]
-b,--brokerAddr create topic to which broker
-c,--clusterName create topic to which cluster
-h,--help Print help
-n,--namesrvAddr Name server address list, eg: 192.168.0.1:9876;192.168.0.2:9876
-o,--order set topic's order(true|false
-p,--perm set topic's permission(2|4|6), intro[2:W 4:R; 6:RW]
-r,--readQueueNums set read queue nums
-s,--hasUnitSub has unit sub (true|false
-t,--topic topic name
-u,--unit is unit topic (true|false
-w,--writeQueueNums set write queue nums
需要指定broker地址 加上-b localhost:10911这样的参数
