Ryan Sasson commented on HADOOP-10709:
--------------------------------------
Refer to
http://hadoop.apache.org/docs/r2.5.1/hadoop-project-dist/hadoop-common/HttpAuthentication.html
for more information. The same configs also apply to hdfs-site.xml (excluding
hadoop.http.filter.initializers) but with the prefix "dfs.web.authentication."
You need to create a jar which contains a subclass of the
AltKerberosAuthenticationHandler class with some custom implementation of the
alternateAuthenticate() method. In short you need to do more than set some
configs in order to enable an alt-kerberos auth handler.

> Currently, we need to define separate authentication filters for webhdfs and
> general webui. This also involves defining parameters for those filters.
> It will be better if one could reuse filters for web apps if desired.
