-------------------------------------
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.
