> Make Hbase Communication Support Virtual Network

>             Project: HBase
>          Issue Type: New Feature

> Hbase only have one way to locate hmaster or hregionserver not like hdfs has two way
to locate datanode used by name or hostname.
> I'm a engineer of cloud computing , and I'm in charge of to make Hbase as a cloud service.
> Our Hbase cloud service architecture shown as follows:  1.jpg
> 1.VM
>     User’s Hbase client work in vm and use virtual ip address to access hbase cluster.
> 2.NAT
>     Network Address Translation, vip(Virtual Network Address) to pip (Physical Network
> 3. HbaseCluster Service
>      HbaseCluster Service work in physical network
> Problem
>      Vm use vip to communicate with hbase cluster, but hbase have only one way to communicate
with each server using host which is setting by parameters hbase.regionserver.hostname or
hbase.master.hostname. When HMaster startup will publish master address and meta region server
address  in zookeeper, then the address is pip(Physical Network Address) . Because hbase cluster
work in physical network. But the problem is that when vm get  the address from zookeeper
is pip, not vip. If I set host as vip, it will has problems for hbase cluster communication
inside. so it needs two ways for communication setting by parameters.
> Solution
>     1.   protocol extend 
>       change strcut ServerName as
>       {code}
>           message ServerName {
>               required string host_name = 1;
>              optional uint32 port = 2;
>              optional uint64 start_code = 3;
>               optional string name=4;  //new field 
>          }
>       {code}
>      It will be publish in zookeeper. We can choose host_name or name configured by parameters
> 2.   metatable extend 
>        Add a column to hbase:meta named info:namelocation . So the original column info:server
configured with hbase.regionserver.hostname, and the new column info:namelocation  configured
with hbase.regionserver.servername
> 3.   hbase-server
>        When regionserver startup, configured  hbase.regionserver.hostname as pip and
configured hbase.regionserver.servername as vip. Then hbase.regionserver.hostname will be
writed in ServerName's host_name, and hbase.regionserver.servername will be writed in ServerName's
name.When hmaster startup, configured hbase.hmaster.hostname as pip and configured  hbase.hmaster.servername
as vip. Then hbase.hmaster.hostname will be writed in ServerName's host_name, and hbase.hmaster.servername
will be writed in ServerName's name.
> 4.   hbase-client
>       Add a parameters named hbase.client.use.hostname to use vip or pip.
> This patch is base on Hbase-1.3.0
