Zhihong Ted Yu commented on HBASE-6433:
---------------------------------------
Looking at the code, Connection has this member:
{code}
private InetAddress addr;
{code}
But I don't see where it is assigned. The following assignment is to a local
variable:
{code}
InetAddress addr = socket.getInetAddress();
{code}
> Improve HBaseServer#getRemoteAddress by utilizing
> HBaseServer.Connection.hostAddress

> Attachments: 6433-getRemoteAddress-trunk.txt, HBASE-6433-90.patch,

> Currently, HBaseServer#getRemoteAddress would call getRemoteIp(), leading to
> call.connection.socket.getInetAddress().
> The host address is actually stored in HBaseServer.Connection.hostAddress
> field. We don't need to go through Socket to get this information.
> Without this patch it costs 4000ns, with this patch it costs 1600ns
