Ajay Kumar commented on HDFS-13492:
-----------------------------------

[~jojochuang], thanks for working on this. Patch looks good. Shall we add 
documentation for this change, since we will limit connectivity to local 
clients?

> Currently httpfs binds to all IP addresses of the host by default. Some 
> operators want to limit httpfs to accept only local connections.
> We should provide that option, and it's pretty doable in Hadoop 2.x.
> Note that httpfs underlying implementation changed in Hadoop 3, and the Jetty 
> based httpfs implementation already support that I believe.
