Benoy Antony commented on HADOOP-10709:
---------------------------------------
The filter used for general HTTP Authentication is configured with all the
required parameters.
If you reuse the same filter instance foe webHDFS, then there is no need to
specify a new set of parameters.
If you want to see an example of how it is configured, please see the xml in
the attached with the jira.

> 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.
