Janus Chow commented on HADOOP-16254:
-------------------------------------
[~hexiaoqiao] [~daryn] For the safe concert, can we add a configuration like
"hadoop.proxyuser.xxx.hosts", maybe "hadoop.proxyAddress.hosts" and the
following policies:
# Router: make sure all requests send by Router have the proxyAddress
# NameNode:
## only requests send by hosts in "hadoop.proxyAddress.hosts" can have the
field of "proxyAddress", or reject the requests.
## the content of "hadoop.proxyAddress.hosts" should be the hosts of Routers.
## NameNode should support dynamic refresh of the configuration in case of
adding/removing Routers.
# Clients:
## Shouldn't set the proxyAddress
## Even the configuration is set, NN should reject the requests since it
connection peer is not in "hadoop.proxyAddress.hosts".
> Add proxy address in IPC connection

> In order to support data locality of RBF, we need to add new field about

> clientHostname represents hostname of client and forward by Router to
