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

             Summary: Implement listStatusIterator, listLocatedStatus for ViewFs
                 Key: HADOOP-14169
                 URL: https://issues.apache.org/jira/browse/HADOOP-14169
             Project: Hadoop Common
          Issue Type: Improvement
          Components: viewfs
            Reporter: Erik Krogen
            Assignee: Erik Krogen
            Priority: Minor


Similar to what HADOOP-11812 did for ViewFileSystem, currently ViewFs does not 
respect optimizations to {{listStatusIterator}} or {{listLocatedStatus}}, using 
the naive implementations within {{AbstractFileSystem}}. This can cause 
performance issues if iterating over a large directory, especially if the 
locations are also needed. This can be easily fixed.
