Allen Wittenauer commented on HADOOP-10878:
-------------------------------------------
In particular, it would be great to lock down:
- metrics
- webhdfs
- hftp
By host and/or user. There are likely others.
> Hadoop servlets need ACLs

> Key: HADOOP-10878
> URL: https://issues.apache.org/jira/browse/HADOOP-10878
> Project: Hadoop Common
> Issue Type: Bug
> Components: security
> Reporter: Allen Wittenauer
>
> As far as I'm aware, once a user gets past the HTTP-level authentication, all
> servlets available on that port are available to the user. This is a
> security hole as there is some information and services that we don't want
> every user to be able to access or only want them to access from certain
> locations.
