             Summary: Refactor AccessControlList to reuse utility functions and to improve performance
                 Key: HADOOP-10659
                 URL: https://issues.apache.org/jira/browse/HADOOP-10659
             Project: Hadoop Common
          Issue Type: Sub-task
            Reporter: Benoy Antony
            Assignee: Benoy Antony
            Priority: Minor


Minor improvements can be done on _AccessControlList_.

Code Reusability:
_AccessControlList_ sanitizes the input list to remove duplicate entries, trim entries. _StringUtils.getTrimmedStringCollection_ can be used in this case.

Performance:
_AccessControlList_  uses TreeSet to maintain set of users and groups.
HashSet improves the performance slightly.
