我启动 hbase.some 区域文件是损坏的块

这个错误是：

HTTP 错误 500

访问 /master.jsp 时出现问题。原因：

Trying to contact region server null for region , row '', but failed after 10 attempts.

异常：java.io.IOException: HRegionInfo 在 -ROOT-, row=keyvalues={.META.,,1/info:server/1354594525394/Put/vlen=15, .META.,,1/info 中为空或为空:serverstartcode/1354594525394/Put/vlen=8} java.io.IOException: HRegionInfo 在-ROOT-中为空或为空，row=keyvalues={.META.,,1/info:server/1354594525394/Put/vlen=15 , .META.,,1/info:serverstartcode/1354594525394/Put/vlen=8} java.io.IOException: HRegionInfo 在-ROOT-中为空或为空，row=keyvalues={.META.,,1/info: server/1354594525394/Put/vlen=15, .META.,,1/info:serverstartcode/1354594525394/Put/vlen=8} java.io.IOException: HRegionInfo 在 -ROOT- 中为 null 或为空，row=keyvalues={ .META.,,1/info:server/1354594525394/Put/vlen=15, .META.,,1/info:serverstartcode/1354594525394/Put/vlen=8} java.io.IOException: HRegionInfo 为 null 或为空-ROOT-, row=keyvalues={.META.,,1/info:server/1354594525394/Put/vlen=15, .META.,,1/info:serverstartcode/1354594525394/Put/vlen=8} java.io.IOException: HRegionInfo 在 -ROOT- 中为 null 或为空，row=keyvalues={ .META.,,1/info:server/1354594525394/Put/vlen=15, .META.,,1/info:serverstartcode/1354594525394/Put/vlen=8} java.io.IOException: HRegionInfo 为 null 或为空-ROOT-, row=keyvalues={.META.,,1/info:server/1354594525394/Put/vlen=15, .META.,,,1/info:serverstartcode/1354594525394/Put/vlen=8} java.io .IOException：HRegionInfo 在 -ROOT- 中为 null 或为空，row=keyvalues={.META.,,1/info:server/1354594525394/Put/vlen=15,.META.,,1/info:serverstartcode/1354594525394/ Put/vlen=8} java.io.IOException: HRegionInfo 在 -ROOT- 中为 null 或为空，row=keyvalues={.META.,,1/info:server/1354594525394/Put/vlen=15,.META., ,1/info:serverstartcode/1354594525394/Put/vlen=8} java.io.IOException:HRegionInfo 在 -ROOT- 中为空或为空，row=keyvalues={.META.,,1/info:server/1354594525394/Put/vlen=15, .META.,,1/info:serverstartcode/1354594525394/Put/vlen =8}

造成的：

1)Verify your DNS settings or what you have given in the etc/hosts
  Hbase requires both forward and reverse resolving of hostname and IP. So add all the slave   
  and master ip in etc/hosts.

2) Check your regioserver file which is inside hbase/conf/regionserver
   remove localhost from every plcae, give somename  if so, because it will not be conflicted.
