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