public class ProxyUserAuthenticationFilter
This file has been copied directly (changing only the package name and and the ASF license
text format, and adding the Yetus annotations) from Hadoop, as the Hadoop version that HBase
depends on doesn't have it yet
(as of 2020 Apr 24, there is no Hadoop release that has it either).
unreleased, master branch commit 4ea6c2f457496461afc63f38ef4cef3ab0efce49
AuthenticationFilter which adds support to perform operations
using end user instead of proxy user. Fetches the end user from
doAs Query Parameter.
