title: how to establish the RegionServer of Hbase to master
body: <p>
  Please tell me how to establish the RegionServer of Hbase to master.<br/>
  I configured 5 region servers, however, only 2 server is worked properly.</p>
  
  <p><hr/>
  hbase(main):001:0> status<br/>
  2 servers, 0 dead, 1.5000 average load<br/></p>
  
  <hr/>
  
  <p>The hostname of this two servers are sm3-10 and sm3-12 from <a href="http://hbase-master:60010" rel="nofollow">http://hbase-master:60010</a>.
  But the other servers like sm3-8 not work.<br/>
  <br/>
  I'd like to know the trouble shooting step and resolutions.<br/></p>
  
  <p>sm3-10:slave, work well<br/>
