-----------------------------------

             Summary: FsPermission#fromShort() should cache FsAction.values()
                 Key: HADOOP-10228
                 URL: https://issues.apache.org/jira/browse/HADOOP-10228
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Haohui Mai
            Assignee: Haohui Mai
            Priority: Minor


FsPermission#fromShort() calls FsAction.values() every time, which causes 
unnecessary performance penalty.
