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). Hadoop
version: unreleased, master branch commit 4ea6c2f457496461afc63f38ef4cef3ab0efce49 Haddop path:
server/ProxyUserAuthenticationFilter.java AuthenticationFilter which adds support to perform
operations using end user instead of proxy user. Fetches the end user from doAs Query Parameter.
