             Summary: Refactor proxyservers out of ProxyUsers
                 Key: HADOOP-10566
                 URL: https://issues.apache.org/jira/browse/HADOOP-10566
             Project: Hadoop Common
          Issue Type: Improvement
          Components: security
            Reporter: Benoy Antony
            Assignee: Benoy Antony


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 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.
