Subject [jira] [Commented] (HADOOP-10709) Reuse Filters across web apps
Date Wed, 11 Mar 2015 08:30:38 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10709?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14356480#comment-14356480

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.

> 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.
