Fei Hui commented on HDFS-13293:
--------------------------------

[~elgoiri] My idea is that there are two issues, one is that namenode should 
log router callercontext which contians real client ip, another is that 
resolving hdfs locality.
The issue that namenode log router context is dicussed on this jara, another 
issue about hdfs locality is discussed on HDFS-13248.
I‘m thinking about ways which are different from  HDFS-13248 posted patch to 
resovle hdfs locality, maybe we can resolve that issue by modifying RBF code 
other than namenode.

> RBF: The RouterRPCServer should transfer CallerContext and client ip to 
> NamenodeRpcServer
