Benoy Antony updated HADOOP-10566: ---------------------------------- Attachment: HADOOP-10566.patch Attaching the patch which fixes the Compilation issue. > Refactor proxyservers out of ProxyUsers > --------------------------------------- > > Key: HADOOP-10566 > URL: https://issues.apache.org/jira/browse/HADOOP-10566 > Project: Hadoop Common > Issue Type: Sub-task > Components: security > Affects Versions: 2.4.0 > Reporter: Benoy Antony > Assignee: Benoy Antony > Attachments: HADOOP-10566.patch, HADOOP-10566.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
