> {{FileSystem}} contains several methods that act as convenience wrappers over calling {{getFileStatus}} and retrieving a single property of the returned {{FileStatus}}.  These methods have a habit of fostering inefficient call patterns in applications, resulting in multiple redundant {{getFileStatus}} calls.  For HDFS, this translates into wasteful NameNode RPC traffic.  For file systems backed by cloud object stores, this translates into wasteful HTTP traffic.  This issue proposes to deprecate these methods and instead encourage applications to call {{getFileStatus}} and then reuse the same {{FileStatus}} instance as needed.
