Hairong Kuang updated HADOOP-6692:
----------------------------------

    Release Note: This issue adds Iterator<FileStatus> listStatus(Path) to FileContext,
moves FileStatus[] listStatus(Path) to FileContext#Util, and adds Iterator<FileStatus>
listStatusItor(Path) to AbstractFileSystem which provides a default implementation by using
FileStatus[] listStatus(Path).
     Component/s: fs

> Add a method  Iterator<FileStatus> listStatus(Path), which allows HDFS client not
to have the whole listing in the memory, benefit more from the iterative listing added in
HDFS-985. Move the current FileStatus[] listStatus(Path) to be a utility method.
