------------------------------------
Summary: RBF should prepend the client ip rather than append it.
Key: HDFS-16495
URL: https://issues.apache.org/jira/browse/HDFS-16495
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Owen O'Malley
Assignee: Owen O'Malley
Currently the Routers append the client ip to the caller context if and only if
it is not already set. This would allow the user to fake their ip by setting
the caller context. Much better is to prepend it unconditionally.
The NN must be able to trust the client ip from the caller context.
