[jira] [Updated] (HADOOP-10566) Refactor proxyservers out of
ProxyUsers
[ https://issues.apache.org/jira/browse/HADOOP-10566?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Benoy Antony updated HADOOP-10566:
----------------------------------
Description:
HADOOP-10498 added proxyserversfeature 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 ProxyUser.authorize() and 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.
