> Key: HBASE-8667
> URL: https://issues.apache.org/jira/browse/HBASE-8667
> Project: HBase
> Issue Type: Bug
> Components: IPC/RPC
> Reporter: rajeshbabu
> Fix For: 0.98.0, 0.95.2, 0.94.9

> Attachments: HBASE-8667_trunk.patch, HBASE-8667_Trunk.patch,

> While testing HBASE-8640 fix found that master and regionserver running on
> different interfaces are not communicating properly.
> I have two interfaces 1) lo 2) eth0 in my machine and default hostname
> interface is lo.
> I have configured master ipc address to ip of eth0 interface.
> Started master and regionserver on the same machine.
> 1) master rpc server bound to eth0 and RS rpc server bound to lo
> 2) Since rpc client is not binding to any ip address, when RS is reporting RS
> startup its getting registered with eth0 ip address(but actually it should
> register localhost)
> Here are RS logs:
