-------------------------------------
[~jojochuang] / [~jeffreyr97], thanks for working on the JIRA. I'm reviewing blockers for 3.1.0, are you currently actively working on the fix? If you don't have the bandwidth to finish/review the patch before Feb 18, can I move it to 3.2.0?

> When we turn on Hadoop UI Kerberos and try to access Datanode /logs the proxy (Knox) would get an Authorization failure and it hosts would should as 127.0.0.1 even though Knox wasn't in local host to Datanode, error message:

> We were able to figure out that Datanode have Jetty listening on localhost and that Netty is used to server request to DataNode, this was a measure to improve performance because of Netty Async NIO design.
> I propose to add a check for x-forwarded-for header since proxys usually inject that header before we do a getRemoteAddr
