Chengwei Wang commented on HDFS-15630:
--------------------------------------
[~elgoiri], thanks for your comment.
I think that split appendClientIpToCallerContext() into two functions maybe
better. We should check whether the context contains current client ip info
first, and then add client ip info to context if needed. What do you think?
