Subject [jira] [Commented] (HADOOP-10566) Refactor proxyservers out of ProxyUsers
Date Mon, 12 May 2014 17:30:36 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-10566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13995284#comment-13995284

Benoy Antony commented on HADOOP-10566:
---------------------------------------

Doing a resend since the mail servers were down last week:

[~wheat9], [~arpitagarwal] , Could one of you please review and commit this patch ?
This is already reviewed by [~daryn]. His comments are addressed. It already passed Jenkins.
The earlier comments related to commits seem to be some error. Looks like,  it was due to
confusion with HADOOP-10556.

> HADOOP-10498 added proxyservers feature in ProxyUsers. It is beneficial to treat this
as a separate feature since 
> 1> The ProxyUsers is per proxyuser where as proxyservers is per cluster. The cardinality
is different. 
> 2> The ProxyUsers.authorize() and ProxyUsers.isproxyUser() are synchronized and hence
share the same lock  and impacts performance.
> Since these are two separate features, it will be an improvement to keep them separate.
It also enables one to fine-tune each feature independently.
