[jira] [Commented] (HADOOP-12050) Enable MaxInactiveInterval for hadoop http auth token

["Vinod Kumar Vavilapalli (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-12050?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15014453#comment-15014453 ] 

Vinod Kumar Vavilapalli commented on HADOOP-12050:
--------------------------------------------------

[~hzlu] / [~benoyantony], the configuration property introduced here doesn't follow our usual conventions (which I concede are not documented in writing). But can we rename this from {{hadoop.http.authentication.token.MaxInactiveInterval}} to {{hadoop.http.authentication.token.max-inactive-interval}}? If you agree, we can get it fixed.

> During http authentication, a cookie which contains the authentication token is dropped. The expiry time of the authentication token can be configured via hadoop.http.authentication.token.validity. The default value is 10 hours.
> For clusters which require enhanced security, it is desirable to have a configurable MaxInActiveInterval for the authentication token. If there is no activity during MaxInActiveInterval, the authentication token will be invalidated. 
> The MaxInActiveInterval will be less than hadoop.http.authentication.token.validity. The default value will be 30 minutes.
