Jean-Daniel Cryans commented on HBASE-1079:
-------------------------------------------

Current code is :

{code}
  public String getServerName() {
    if (location == null) {
      return null;
    }
    return location.getServerAddress().toString();
  }
  public byte[] getRegionName() {
    return location.getRegionInfo().getRegionName();
  }
{code}

getServerName was fixed some time ago, now we need to fix getRegionName.
