how to establish the RegionServer of Hbase to master

Question

Please tell me how to establish the RegionServer of Hbase to master.
I configured 5 region servers, however, only 2 server is worked properly.

---

hbase(main):001:0> status
2 servers, 0 dead, 1.5000 average load

---

The hostname of this two servers are sm3-10 and sm3-12 from http://hbase-master:60010 . But the other servers like sm3-8 not work.

I'd like to know the trouble shooting step and resolutions.

sm3-10:slave, work well

sm3-8:slave, not work properly, however, the status looks good

检查以确保在所有主机上都正确配置了dns，并且每个服务器都可以进行反向查找
