--------------------------------------
Summary: Make AuthenticationFilter @Public
Key: HADOOP-14998
URL: https://issues.apache.org/jira/browse/HADOOP-14998
Project: Hadoop Common
Issue Type: Sub-task
Affects Versions: 3.0.0
Reporter: Robert Kanter
{{org.apache.hadoop.security.authentication.server.AuthenticationFilter}} is
currently marked as {{\@Private}} and {{\@Unstable}}.
{code:java}
@InterfaceAudience.Private
@InterfaceStability.Unstable
public class AuthenticationFilter implements Filter {
{code}
However, many other projects (e.g. Oozie, Hive, Solr, HBase, etc) have been
using it for quite some time without having any compatibility issues AFAIK. It
doesn't seem to have had any breaking changes in quite some time. On top of
that, it implements {{javax.servlet.Filter}}, so it can't change too widely
anyway. {{AuthenticationFilter}} provides a lot of useful code for dealing
with tokens, Kerberos, etc, and we should encourage related projects to re-use
this code instead of rolling their own.
I propose we change it to {{\@Public}} and {{\@Evolving}}.
