Arun Suresh commented on HADOOP-10709:
--------------------------------------
[~rsasson], thanks for the pointer..
What I was referring to was the fact that if you configure normal Kerberos in
hadoop.http.filter.initializers in core-site.xml and have an AltKerb subclass
configured in dfs.web.authentication... in hdfs-site.xml, The AltKerberos
filter will in-effect be of no use, since all requests will have to go thru the
other Kerberos filter anyway.
> Reuse Filters across web apps

> 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.
