Subject [jira] [Commented] (HADOOP-9479) Ability to plugin custom authentication mechanisms based on Jaas and Sasl
Date Tue, 23 Apr 2013 19:45:17 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9479?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13639479#comment-13639479

Daryn Sharp commented on HADOOP-9479:

I've only skimmed the patch, but I'm unclear what benefit this custom layer provides that
standard java security providers and factories do not already provide? 

bq. [...] it allows introducing additional methods in the future without the need to enumerate
all of them in UserGroupInformation.AuthenticationMethod.

I already plan to abolish this, perhaps with the RPCv9 sasl changes.

The new authentication mechanism should have both Jaas and Sasl implementations.
